I'm tired of my barber touching my face so I stopped using them.
Why does your barber touching your face bother you?
I refuse to assume how he touches the face of other customers, but I could see it in his eyes that he wanted to touch my face.
If you're unable to talk to your barber about what makes you uncomfortable, you're well within your right to find a new one. It's important that you both feel satisfied with the business transaction.
I wanted to be discreet about it but I will switch.
Thats okay and I hope your new barber works out for you. If you continue to have issues you may want to talk to this one and find out if maybe thats just what barbers do? That way you can feel more comfortable with your new barber.
