Bathroom Hygiene

Whenever I am at a public restroom, I always try to minimize touching anything in the bathroom. Many public bathrooms have auto flushing toilets but those are usually find in upper-scale establishment, probably because they are costly. Manual toilet flushing is prevalent, and touching the handle always gives me the creeps. 

These kind of toilets just don't make any sense to me. How about a pedal for flushing?
