Here is my tip of the day:
when some loser at a chip wagon that is too drunk for his own good dumps your fries on your head, it helps to jump up on the table and jump over the other side like a mad woman, it helps to make you look just crazy enough to intimidate him, just before you let him have it.
Caveat: he might scratch you and run away like a little girl, after you boot him in the nuts.
