I've shit one singular time in a "public" toilet in the past 25 years besides workplace bathrooms, and Porta potties while camping. Workplace or Porta potties both have hand sanitizer which I take copious amounts of on my way in, drip off my hands onto the seat and wipe it down with TP. Rub the rest of the sanitizer on my hands, and eviscerate myself with the equivalent power of 10 men's shits in 30 seconds.
