I can't think of anyone who is a fan of bathroom attendants. Other than being fodder for jokes (like this bit by Amy Schumer) they serve no purpose. I think at one point it may have been a sign that a place was classy but that day is long gone.
Over the weekend I was up at Saratoga and they have bathroom attendants at the race track. I got to thinking about how unnecessary they are after I went into the bathroom before the eighth race and the bathroom attendant was sitting there eating his lunch - an open faced roast beef sandwich. It was just wrong eating in the bathroom like that.
I got to thinking that it probably would be pretty easy to discontinue the practice of bathroom attendants. You would simply get a woman to sue for the right to be a men's room attendant and get a guy to sue for the reverse. With trans-gender folks able to use the bathroom of their choice these days and the inherent potential discrimination of men's only or women's only jobs - it's a good chance those cases would win. How classy would a place think it would be to have a male attendant in the women's room? Creepy right? And would a guy see a woman in the men's room without thinking "Is she a prostitute?"
Bam! No more bathroom attendants.
