I have had the owner of a restaurant get annoyed at me because she was on the telephone when I walked up with my money. And the service is as bad up here as it is in the back. Making customers feel stupid is another joy many employees and business owners seem to take. This can happen by accident and most likely the majority of the time that is the case. The electrician is called back and, of course, the light works for him.
Customer service goes beyond the physical location of a business.
There is one service in town which has a little truck with the business name proudly emblazoned across it. The person behind the wheel has absolutely no concept of what it means to obey laws or be a courteous driver. He runs stop and yield signs as though he is blind, he tailgates and he races at a very high rate of speed, right beside cars in a construction zone when his lane has barricades, then he cuts the car off then slams on his brakes. Keep in mind the simple things, to smile, try, acknowledge and respond. Be aware that in company uniform or vehicle you are still providing customer service even if you aren't directly dealing with people one on one.
