How to Share Plates and Utensils

I feel like sharing plates and utensils and stuff is fine as long as people are usually good about cleaning up after themselves especially because depending on how many people you're living with it would take up a lot of covered space to share. I've heard of people will either keep it in the room normally or they'll just like store it in a less obvious spot to reduce the possibility of getting it accidentally mixed up with other things. The one thing that drives me crazy is that they never fill the Brita filter so if you want to drink water you have to fill it and then you wait probably three minutes or so for it to all drip down.
