Yeah man, IMO, people need to clear there bong rips. That way I don't get any stale smoke and a nice fresh rip of my own. plus, if you don't clear it the person that had to fill the chamber for there hit isn't getting nearly as much as someone taking a hit with the chamber already full.

You are are doing it right. And if you are supplying for the sesh, who are they to tell you how to smoke your weed? Unless it is to help you get a better hit that is.
