I am very phobic of public toilets. For emergencies, I have a 'poop kit' in my car...it is in a little bag and has foaming sanitizer, paper towels, and a ziploc with wet wipes. If I HAVE to shit, I try to select an upscale location likely to clean their restrooms well. Once I get in the stall, I coat the toilet seat in the foaming sanitizer, then wipe it off completely with the paper towels after giving it 30 seconds to sterilize the seat. Only then can I bring myself to sit down. The wet wipes, obviously, are for proper post-poop cleaning, cuz just using that cheap ass public washroom toilet paper isn't good enough.
