Was having a conversation with a neighbour about general this and that and our window cleaners came up - she mentioned that she tips them every week. I didn't ask how much but i don't do this Am I mean and tight fisted? I do at xmas but not every week surely? I really don't know if this is what you are meant to do, it's never come up before, and my windows still get cleaned!
So AIBU not to tip them? And what do you do for other things e.g hairdressers (I'd say yes), taxis (depends), waiters etc(yes).
I'd hate anyone to think I was taking advantage of them by not tipping but how on earth are you supposed to know????
