Imagine the old time barbers who had to shave everyone who came into the shop and in those days a BBS and comfort was the norm, it was expected. Anything else and the barber might find himself deep-sixed by the customer.

The trick is to learn to map out your beard. Once you learn that lesson well you can shave anybody no matter how different the individual beard might be. A few minutes of serious faceturbating can pay big dividends even if you're not a professional barber.
