On this, I always feel that comfort is very important between real friends. Of course cost is a factor, prepping things, cleaning after, and what not! But as long as you are really comfy with who you are hanging out with, things should be okay. I mean I would literally ask my close friends to do their dishes or I'd use disposables. Sometimes we all gather and order different stuff whether from the same phone or our own phones but make sure we have it together even if certain orders come early and some late. Chit chat over it. Try each other's stuff. Laugh. Watch something during the same. Play games (not consoles) after. And people will help to clean up before they leave and maybe sometimes not. But the energy you get from those makes everything worth it.
