Q: It's your turn , sir . I'm sorry that you had to wait . Saturday is a busy day for us . I suppose so . A haircut , please . How do you want your hair cut ? Any particular way ? I'd just like a trim , and don't cut it too short . Yes , sir . How about the sideburns ? I think they only need a little trimming . Can I use the clippers ? No , don't use them , please . Oh , all right , sir . Would you trim off a bit more there , above the ear ? Don't you think it needs a little taken off on top , too ? I guess that would be better .
