I was going to start my own topic about restaurant magic myself, but seeing as you beat me to it, i'll post my question here.
It's about tips mainly, I was wondering how do you actually get the fact across to the audience you are working for tips, or well would like a tip
Do you just tell them, "Hi I'm _______, the house magician could I entertain you with some magic for 5 minutes, oh and I accept tips"
...doesn't sound all too well..
I've seen David Stones The Real Secrets of Magic, and he seems to say you should just hint it, or joke it for example:-
"can I borrow a note please, *as they reach for their wallet* just something small, save the big ones for the tips

"
But what if your not doing any money magic? any other ways of hinting subtly, without a big badge saying "working for tips"
