What more could you say about the reasonable price tag when SuperCuts haircut prices for adults is just $12.00, $10.00 for children 10 years old and under, and a senior citizen discount at $10.00 for adults 65 years old and over.
I'd say, haircut-wise, under the $100 (excessive to me at least) level, the cost reflects the time and detail spent on the haircut, therefore 20% makes sense. For instance, at my last job I charged $30-35 for a men's cut and $50-55 for a women's cut.
