Would the personal space issue also apply to putting sauce cups on andy's* head?

*not his real name.
I also did that to another person as well. I guess that wouldn't be bodily fluid. So would that be normal?

Since I couldn't tell the difference between me joking around and other people doing the same thing, maybe I'll benefit from not joking around. Maybe it's the context or w/e, but it baffles me that those tiny unnoticeable details make all the difference.
