Went in and ordered a "classic" hair cut. According to their prices, this is 150Kc. After getting a…read moresatisfactory cut, she asked if I wanted my hair washed. I asked if she could rinse it out. Instead, she shampooed (twice) , "styled" my hair (which I declined when she asked if I wanted it), and then blew dry my hair while preening it with a brush. All this nonsense for a classic crew cut that I told her I didn't want styled, etc. What should have been a 150kc haircut, she charged me 270kc for.
This is typical of barbers in Prague, unfortunately. Rather than getting a permanent, repeat customer, they'll rip you off for an extra couple of bucks.
If you go here, decline *everything*. If they start doing anything you didn't specifically ask for, tell them to stop, otherwise they'll charge you extra.
Spoke in Czech the whole time.
