I came to get a haircut under one nozzle in front of the army. during the haircut, the machine pulled out the hair, then discharged, cut another one, which tore the hair even harder and also discharged. somehow they got a haircut, recharging the car several times, and in the end they didn't even wash their hair, although it was covered in short hairs.
this pleasure cost 17p, I highly recommend this barbershop
