[Since then, if I have to pay a bill of less than 500 with a 1000 note in a bar, I say '1000' to the waiter and make sure he understands I know what I've given him.]


I do the same. It makes life so much easier. I always state the big not to the person and look them in the eye. Trust me it works. Also makes you know your not going mad and question yourself if you made a mistake! Too many crooks out there.

And if I have been given too much change, I will own up and let them know. It works both ways.
