I know everyone wants to get that last customer in. Then out the door before the store closes.
And I know, every stylist doesnt know every hair style trend or perm technique. Granted. But, in any barber or cosmetology school. They teach basic ethnic hair cutting technique. And if you just can't do it "refer it"
Don't do it. Ask if it is ok. Then expect a tip..
But, like the commercial says "they don't cut better than other places, they listen better" Hmmm..
