The 1960’s were NOT before my time, and I’ve never come across this, in Texas or anywhere else. Of course, I never stayed in 5-star hotels either. … Take that back-- actually I have a time or two.
The Motel 6 definitely does not do this. But they do leave the light on for you.
After reading the article, I suspect the author was talking about his and her sinks, akatwin sinks. There’s nothing particularly 5-star about them; I’ve seen them in a lot of Holiday Inns and the like. By itself it would be indicative of only a slightly larger vanity area than the tiny rooms in the New York hotels the author was more familiar with.
