Yes
You are being totally unreasonable

I have found myself having to raise my voice on numerous occasions when wearing a mask. There have also been many times when folk wearing masks have had to do the same when talking to me from 1 metre distance. I am not alone in this and I think there's no doubt that that masks muffle speech. On the assumption that the security person was socially distant, could it be that she was merely ensuring she could be heard?

I would have been embarrassed, would have said ‘Oh, I’m so sorry, this is the first time I’ve been in here for ages’, and would quickly have gone out of the correct door, hoping no one I knew had seen me.

Just imagine how many people deliberately use the wrong door and make her cross.

I do not think you were unreasonable you just had not used the store for a while and did not know the new arrangements.
If you were almost outside then maybe just keep going it was a genuine mistake.
Our Sainsburys store does not have the security down at the door anymore, what they have are entry door and exit door
and they have put those heavy orange barrier type things up so you have to use the exit door, before covid you could walk out the entry door depending on where you have parked your car.
Last week as I went in the entry door to go to the escalator
two men came down the escalator and apparently they did not want to use the exit door so they kicked the barrier down narrowly missing my leg and went out the entry door.
Two other men were shouting at them from the escalator for their stupidity and the security was just standing looking at them from the top of the escalator. When I got to the top of the escalator I said to the security you should be on the doors downstairs he just said no we have got the barriers down there so I told him to send someone to pick up the barrier as he had just seen them being kicked over. People are now acting like the covid has gone and it is turning into a free for all.

No. Someone at the surgery was rude like this to me the other day when I picked up my tablets. They had changed the 'system' and it was confusing to me so I went the wrong way. I was feeling upset, but the lady dispensing the medication was lovely, which made me feel better.

It's happened to me a few times, when 'in a dwam,' especially in Tesco's...although I've not been shielding. I always feel embarrassed and retrace my steps. However the staff are always polite in pointing out the error of my ways...

kircubbin2000, you haven't been out in a year so, obviously, you've been unaware of the changes introduced for safety.

Shops have tried hard to organise a safer, socially distanced, one way route through the store.

Therefore, your doing what you always have - was wrong!

I understand these are difficult times but everyone deserves to be treated with courtesy and respect. You were in there to spend money, money that ultimately pays the staff wages.
I would send your email to the Chief Executive of Sainsbury’s, the assistant was rude and shouldn’t have spoken to you like that under any circumstances. There are tactful ways of getting the message across.
I hope you don’t return to this supermarket. Are there others that you could use that value your custom more?.

I went to Sainsbury yesterday, my weekly visit. It's quite a small one, and usually not busy at the time I go. I noticed that they have now put up large 'Exit only' signs on the exit door - which has always been the exit door. There was the usual single staff member on the entrance door but no queue so I went straight in. A woman pushed past her on the other side to me with no mask. The girl asked her to wear her mask while in the store (she should have had it on anyway as this is in a shopping centre) and was told to 'f.. off, no one can make me wear a mask if I don't want to'.
As I was paying I heard a bit of a kerfuffle behind me and saw two men, again maskless, pushing their way into the shop through the 'Exit only' door, fighting against the people leaving. The Lord only knows why, it's only about 15 feet away from the entrance door.
I was only in the shop for 15 minutes. If the security people are putting up with this for 8 hours a day I'm not surprised they are frazzled.

Sending an email to the CEO of Sainsbury's is an over the top reaction in my opinion. It just blows the whole incident out of all proportion.
The security guard shouldn't have been rude, he/she was wrong, but so were you.
Their lives are pretty difficult, with extremely poor pay into the bargain..

send your email to the Chief Executive of Sainsbury’s, the assistant was rude and shouldn’t have spoken to you like that under any circumstances.
The security staff are not normally store assistants, but employees of a security company, probably paid even less than the Sainsbury's staff.
I'd have admitted my mistake apologised for not noticing.

I think the email would be OTT. However if you go ahead, the CEO might well ask to see the video footage of the event.
If he sees that, he will see how long the exchange lasted and the fact that you ignored the rules, however brusquely they were given.
Since there isn’t audio he/she will have no way of knowing exactly what was said, and I hope you were both wearing masks, so no chance of lip reading.
It was upsetting for you and possibly for her as well, but better to let it go. You’ll be much more aware next time.

It would have been a last second decision whether to continue on out the door you were using or to follow the yelled directions. I probably would have been a little annoyed at the employee’s angry tone so I might have kept on going.

Since no one else was around, it did not really matter.
Just remember,
Common Sense is no longer that Common.

Box ticking is much more important.
