Okay, I am honest with you all .
I always tip the delivery man at least $1.00.
Sometimes if I am in good mood, $2...and keep the change also.
I tip the uncle who send me home from the airport. Sometimes $5 and $10
If I am lucky at the casinos, sometimes, i tip the taxie from the casino rather generously.
It is always good to tip delivery boys.They work hard and most of them come from dysfunctional and poor families. I tip them , talk to them, encourage them and thank them in person. Most of them are students earning some pocket money...
