How many plates do you eat at a buffet?

Going to a buffet and only having one plate is a colossal waste. I am a fan of arbitrary rules I set for myself, therefore I have a three-plate minimum/five-plate maximum when I buffet. Sticking to these guidelines I generally leave having tried one of what I would like to try, and leave without totally over doing it.
