Never in my life have I seen an public restroom so clean. Perhaps that is why it is kept under lock and key. It threw me off a bit to have an indoor convenience store toilet require a key stuck to an over sized object, but it was worth it upon entering.
Not only is the restroom clean, but the grounds outside around the pumps are also clean. The coolers were fully stocked and there weren't even messes around the slushy machine.
