You see this in old cartoons, TV and films–the hot towel, open blade, etc. I realize this was before safety razors, but a clean-shaven man has to shave every day (haircuts are not daily), and that might add up, depending on the charge. If a shave and a haircut were really two bits, was that a luxury or normal, everyday expense?
Also I wonder: Can I go to a barber today and get a shave? How much would they charge?
