I dunno, healthy stuff is one thing, but a squirt is just an unpleasant thing to be around.
Plus, as ripper points out, an office toilet is one thing, but you don't want to loiter around a public restroom. Watch out for coprophages, and if possible use your intel to figure out which public restrooms are used for OOS ("Operations Other than Shjtting"), lest someone pull a george michael on your ass.
