Tips are extra.
You don't need to give tips.
Yes, if I worked in a restaurant I would like to get tipped, but I wouldn't get pissed off if I didn't.
I tend to tip the change and no more, because it is my money, I have earned it and it isn't as though I have loads of money to just give away.
I really don't mean this in a nasty way, but if the pay is so terrible, why do so many people do the job? That baffles me... there must be other work out there that pays a living wage.
Is there a tipping wank bingo card yet? Because I think I could fill it up on this entry.
