I've always read (the etiquette gurus) that it isn't necessary to tip service people who own the business ~ such as a nail tech, hairdresser, aesthetician, etc. Do you tip these providers if they are the business owner?
The guy i get a haircut from owns the barbershop, i hook him up accordingly20-25%...but in the city where drinks can cost 8 bucks, i say fuck it, 1 dollar or nothing...its a rip off....depends if the service/commodity is worth it.
