Has he been able to solve the problem of bridging the gap between the bathroom stall and the waste bin? Ir does he flush them? Most stalls in the colonies don't have waste bins in the stall. So you are faced with the problem of how to dispose of your dirty nappies. If you walk out of the stall to the vin before going to wash your hands you will be on the business end of some odd looks. This why most wet wipers flush. There are, however, alternative methodologies.
He owns his own business (funeral home) so he has his own bathroom for employees. He's hardly ever at a public restroom so I don't know what he does. I recall him carrying around a 10 pack of disposable wipes so he probably flushes them.
