I always ask for a "regular haircut", but the haircuts I get with that request can differ a lot. Sometimes I get a quick buzz around the ears and neck, and other times the barber chooses to use scissors for that and really takes his time to get everything looking neat. In all cases the haircut is satisfactory and I'll come back (I've been going to the same barber for 10 years), but when he's in the mood to take his time I'll give him a tip. > charge for what it costs I think that's a bit tricky, I don't think the true cost of a haircut is fixed day to day. On slow business days when there is no line, a slow and careful haircut doesn't really 'cost more' than a quick haircut because the daily throughput is the same. But on days when there are a lot of people lining up for cut, slow haircuts will reduce throughput and therefore have an opportunity cost. (This is for a walk-ins only barber.)
