Yes I thought about that when I wrote it! It's been a long time since me and her did anything like that though!
As for complaining about a meal, I don't remember ever doing that either, so i guess I've been lucky. It's shit service, especially having to wait ages to be served or get the bill, that really annoys me. It actually puts me off ordering food here in the UK - I'm always thinking how long it's gonna take to get served, especially in pubs. I start getting pissed off if I'm waiting longer that 15 mins, and if I have to wait longer than 30 mins I'm so angry that it ruins the meal for me, no matter how good the food is. (Yeah I know - it's usually not a good idea to eat out with me!). The last instance I remember was at my local the Dartmouth Arms (NW5) when we had to wait about 50 mins for a breakfast - the girl who served us did at least apologise but then she added insult to injury when she asked 'did you move tables?' - kind of implying that it was our fault it had taken so long, when we'd been sitting at the same table all the time! (and she damn well knew it too). So that's another place I've never forgiven and haven't eaten in since.
By complete contrast I love eating out in the US where I can't remember ever having to wait more that about 15 mins to get served anywhere. It always amazes me how fast (and usually pleasant) the service is over there. It really shouldn't do - it's just that I'm so used to poor quality service because I'm British!
