Never hid in the toilet...but at a couple of assemblies and conventions I've gone shopping for an hour or so. Left everything at my seat except my bible (needed it to hold my license and car key) and put on the look/walk like I had a big assignment I had to hurry off to...you know the look/walk I'm talking about. You had to time it just right...leave right after a song and then come back in the middle of a song
Funny thing was, I ALWAYS encountered other witnesses!
