It depends on the barber. Some chat a little, because it keeps them occupied. I’ve never had a barber try to talk my ear off, but a little light conversation here or there is expected. Then there was the time I went to a place that only did tight fades. The conversation was as follows:
Barber: Are you in school?
Me: No.
Barber: Do you have a job?
Me: Yes.
Barber: Well I’ll be damned…
[end of conversation until haircut is completed]
Now that I cut (what’s left of) my hair myself, I don’t have to worry about talking to barbers, so I’ve got that going for me.
