Having had hubby stand guard at more than one “one-holer” while traveling where the ladies’ room was out of order (if there were no gents waiting to use it), I quite assure you...a toilet is a toilet, a sink is a sink, and a hand dryer is a hand dryer.
“I assure you, when you GOTTA GO........”
That didn’t work out too well for me years ago in New Orleans. :)
