A soldier walks into a barber shop

and, seeing that both the barbers are busy but there is no-one else waiting, takes a seat. Just as one of the barbers finishes with his customer, in walks an officer. The officer quickly appraises the situation and sits straight down in the one vacant barbers' chair. "An officer on a weekend pass to see his wife takes priority over a private who's going to spend his weekend in a brothel." says the officer. The soldier just shrugs, seeing that the other barber will soon be finished.
The first barber asks the officer how he'd like his hair cut, and the officer says "The neatest short back and sides you can manage. It's important I look my best for my wife, not like some enlisted man spending his weekend in a brothel." So the barber sets to work with his scissors .
By now, the second barber is ready for the private, but he doesn't bother asking the private how he'd like his hair cut, he just quickly sets to work with his clippers.
Once the officer's hair is finished, his barber asks whether he'd like any pomade to dress his hair. "Absolutely not," says the officer. "I wouldn't want to appear in front of my wife smelling like I'd spent my weekend in a brothel."
As the second barber finishes clipping the private's hair cut, he asks him if he'd like anything in his hair. "Why not," says the private, looking over at the officer. "My wife has no idea what the inside of a brothel smells like."
