What do you pay for a haircut?

I buy a ~$35 clipper every 20 years or so.

Supercuts type place is about $24  here , I usually leave $30

But I have not found a good place to trim my beard , so do it myself  when it gets too long.....

As far as $30 for 20 minutes being too much , well yeah 3x$30 every hour is great money , but what barber has  3 customers an hour all day , everyday ?

a guy called Chuck in my hometown had a one chair shop next to a drive- in movie theater and some car dealerships. In the front window he had a homemade sign with about eight trailer tail lights. The lights indicated the number of customers waiting inside. So you could decide to stop in now or come back later.
I don't think I ever saw Chuck spend more than ten minutes on a haircut and the shop was often full. I last visited the shop three decades ago and I am pretty certain he is retired now. But three haircuts per hour is very possible.
