Shave-O-Mat

Harry Thalheim believed that “a need has existed for a long time for a shaving emporium where people may shave cheaply and rapidly at all hours of the day and night.” So, in 1964 he patented the Shave-O-Mat (US Patent No. 3,120,886). It was a coin-operated shave-yourself establishment, open 24 hours a day.

Did this address some kind of market need in the 1960s? Were there men who, in the middle of the night, really wanted to shave but couldn’t?

I'm guessing not, because, as far as I can tell, Thalheim's Shave-O-Mat never opened.
