I am a great believer in either both complain and praise when appropriate, or say nothing . For a role model rather than Victor Meldrew I prefer Stephanie Cole in Waiting for God. More my kind of person! The assumption that if you are older you may be spoken to as if you were an idiot or a child annoys me too. I certainly complain if necessary, so for example young man on checkout starts banging fruit down.Pears especially dont like being treated roughly so dont think he will do that again in a hurry, But at the same store on another day, a most helpful checkout person who put my shopping into bags , as my back is really bad at the moment , was most pleasant and helpful , and even when I went out to the car park the very nice young man dealing with trolleys came across unasked and lifted the bags into the car for me .So I went online and commended those people to the bosses and this will be , I hope, a good point for them. I was head of communications for Great Britain , for a large company and you do find that whereas most people will be polite and thank people on the spot, they rarely bother to put in writing in some form. Whereas complaints will be voiced but often written in, so it is rather a biased slant, if you look at comments on a specific person. I also some time ago went into my local Tesco and they did not have a disabled buggy to use. I queried this and was told various things - store not big enough , nowhere to keep it etc etc. I spoke to someone and did not feel I got anywhere so went higher up the chain and carried on lobbying, politely but also reminding them that it would benefit them as those of us who cannot stand or walk round , would be able to do their shopping and get all they require and of course Tesco would get the money. So it took a little while but now there is the needed buggy, and in the beginning it looked as though I was the only person using it. But now you can see (you have to sign in and out for it) quite a lot of people have been able to get round and it makes a difference to lots of people , and well done Tesco for this and their blue token charity support etc. Probably in the beginning I was seen as a very annoying customer but think they now see it has been worth it. Yes I think we should all expect civilised and polite behaviour , but of course include expecting it of ourselves
