Siferous

I dont know if this is in the right section but whatever. I was just curious to see how many people out there when smoking with you friends or anyone basically packs an entire bowl for themselves and everyone else in the group also gets a full bowl, or is the majority of people out there smoke a bit of a bowl then pass it around untill it's gone?

The only reason I ask is because on these forums I see posts about bowl rules and stuff, and in my group of friends if you pass someone an unfinished bowl you get laughed at and forced to finish it.
