I have not told anyone how they should behave. My opinion is just that, it's what I would do were I in that situation, and it's what I think would be the sensible thing to do. I said what I said because the OP hadn't made the waitress aware of her requirements, so I merely thought it would be sensible to make the waitress aware of that. I fail to see why you have been so critical of my opinion when you have, in fact, stated yourself that that is what people in your situation do anyway. So, aren't we basically in agreement?
I have worked with children, some who have had severe food allergies, and I've been witness to a child going into anaphylactic shock, and required his epipen to be administered. My DiL has a food intolerance and needs to be very careful when eating out. My husband is diabetic, and eating out can be a challenge. And my DD runs her own business within the food industry. I base my opinions on the knowledge that I have, and totally realise the seriousness for people who have allergies/intolerances/specific food requirements. So, again, I don't know why you have been so critical of my opinion, which to me, seems very reasonable.
You've also stated how helpful you find restaurant staff to be, so again, I fail to see what your issue is. You did make a previous comment about how some people with allergies/intolerances are treated not so well by staff, and perhaps, going back to the OP, this is an example. However, the OP was served a sandwich with a relish she didn't like and wasn't expecting. She waited until she had scoffed the whole sandwich before bringing it to the attention of the waitress, and then went on to question her about what if she'd had an allergy. The waitress quite rightly (in my opinion) said that they expected customers to make them aware of any allergies in advance. As this is something that people with allergies apparently do anyway, the waitress would've relayed the information to the chef, and the OP wouldn't have had the chilli jam on her bacon & brie. So the situation wouldn't have arisen would it? In an ideal world, the waitress probably should've responded with an apology, and told the customer that if she dined with them again, she would make sure not to include any food she didn't like ... as long as she was made aware of it when ordering.
In response to your following comments ...
PippaZ"Oh and if the difference of opinion you refer to is putting customers before staff - I'll stick to mine thank you very much."
I honestly have no idea why you think that, as it's absolutely not the case
.
PippaZ"What I said was deliberate you seem to be completely unaware of how rude, at the very least, you are being."
I assume you are referring to my comment about staying at home? Even though you say that staff are very helpful, you seem to find eating out a challenge, and extremely stressful. Apologies for my thoughtlessness, and inadvertent rudeness ...
PippaZ"What I said was deliberate you seem to be completely unaware of how rude, at the very least, you are being."
But I guess it's OK to be deliberately rude, particularly when you don't agree with someone?
We all have different opinions, which we are entitled to, and often, when someone doesn't agree with your opinion they deliberately misconstrue what are saying.
