The barber man or barber is too dependent on tips. Selective when serving new people who have never been there. invited to talk about haircuts are also less wearing. Because yes, that was the point at the beginning, they felt 'oh at least this person will not give a tip or the tip is small.
Even though we people want to give tips because we saw what his service was like at the beginning. If the first impression we shave is not comfortable and the service seems rushed and rude, why give a tip?
Please use it as an evaluation. Don't worry, everyone will give you a tip if your attitude applies to us. Apart from that for the admin section, or the staff at the cashier, there is no problem. Serve in a professional and responsive manner. thank you
