I hate that. At the place I go there's a bunch of barbers and I just go to whoever is free. The last couple times 2 different guys have trimmed my beard/chinstrap without asking if I wanted it trimmed, and then they charged me extra. I just told them to cut my hair with a 2 and do a shapeup while leaving my sideburns attached to my beard/chinstrap, and more than once they just started trimming/lining up my facial hair too. It sucks paying more cause I could just do that at home.
Shit, well that's more annoying than mine. My dude comes to my brother's after hours which is cool but if I say fade the sides from a 2 to a 1 & he does from 1 to 0 more than once your gonna start getting annoyed he isn't paying attention. The cut still looks good but that's not the point...it's not what I asked for.
