I have been bringing my two boys for a while since they had some pretty gnarly haircuts at other places. EVery stylist has been awesome and super kind. Great Hair cuts too!
The tip choices on the kiosk when I check out are a bit crazy. For two haircuts ($54), the options given were $16, $18 and $22.
$22 would be a 40% tip! I tipped $14 ($7 per haircut) which was below your lowest option but still calculates as a 26% tip. It was a little intimidating to give a good tip but it still be lower than the lowest option given.
