My grandfather is a succesful barber. Still working 65 years later and has nine chairs in his shop. Only works because of the social aspect of it. A true old time barber shop complete with the good ol’ boys sitting outside. He caters to a blue collar town.
I asked him once how he fairs during recession. He told me business is always up during that time. Claims it is a cheap way for people to keep thier self-esteem up or looking good incase of a job interview. Hence he does better.
