What's the one thing you always check on a porta potty before using it?
After nine years driving a vacuum truck and a lifetime of using these things at county fairs and construction sites, I have a set routine before I step inside a standard portable toilet. The first thing my eyes go to is the floor, right inside the door. I'm looking for mud, standing water, or anything that suggests a leak or a recent flood. A wet floor is a bad sign. Then I check the paper situation. Is there any? Is it dry? After that, it's a quick sniff test, but the floor tells you more about the last user and the last service visit than the air does. I figure other folks who use these daily have their own checklist. What's the absolute first thing you check when you crack that door open? Is it the lock, the seat, or something else entirely?
