But you wouldn't get a queue for paper towels. People would grab 2 or 3 towels and move aside.

Maybe but there's a bit of a shuffle getting around people who have grabbed towels. And there are always the people who stand by towels to dry because that's where the trash can is.

Actually, I guess separating the towel dispensers and trash cans in existing bathrooms would be a smart efficiency move since it would encourage people to grab a towel and keep moving.
