The reason the barber raised his fee from $5.00 to $7.00 is because you were too cheap to tip! Tipping is customary in that profession and is part of his income. He has become quiet because he has nothing to say to a cheapskate. You have insulted his work. The barber is hoping that a price increase and the silent treatment will send you down the street to one of his competitors. It has worked beautifully!
He has probably told all the business people in town that you are a cheapskate as a public service!
If you never liked the barber or the atmosphere of his shop, why did you keep going there? Because you are a cheapskate and that was the cheapest place in town to get a haircut. Now, you have to go down the street and pay more. Did you learn anything, or has your narcissism blinded you from any insight?
