RudeMech saidIs this a growing trend?
Perhaps more of a dying trend in many places in the US. It's not uncommon in finer restaurants, nightclubs, hotels, and a few other exclusive places. And sometimes in high-use public restrooms, essentially performing a continuous janitorial role, and not really there to serve anyone. I appreciate the overall cleanliness it ensures, with all necessities kept in fresh supply, but neither do I feel I need such individual attention to my own person.
A few years ago I took a friend to Tavern on the Green in Central Park, NYC, before it closed down. The men's room attendant handed you a cloth towel at the sink, not paper, and warmed as I recall. My friend went in a little while after I had, and upon exiting claimed the attendant had actually dried his hands for him.
I was a bit incredulous, since that wasn't the treatment I had gotten earlier, nor would have accepted. But then my friend was certainly more attractive than me, and with more of the "I've got money" look about him than I do. And though he insisted no one ever suspected he was a closeted gay, in truth he practically had it tattooed on his forehand, so perhaps the attendant was hitting on him.
In any case, the rule when going to a venue that might be a bit upscale, especially where a coat & tie are typical, is to have some loose bills at the ready, most conveniently in a money clip so you don't have to drag out and open your wallet or billfold in public. (I have several money clips that match my cuff link & stud sets for the most formal occasions, and I forego a wallet altogether)
You must anticipate the need to tip parking valets, bartenders, maitre d's, room captains, a whole legion of people, to include men's room attendants. And of course if you are escorting a lady, you will politely ask if she needs "change" when she excuses herself for the ladies room. Most well-bred women will not, but you must be prepared if she answers yes, or realizing her own oversight, prompts you for it herself.
