I worked 3 years in fast food and I am coming up to year number 2 at a call center. I have learned to never in a million years get mad at the person on the phone or standing in front of me. 9/10 they are doing what their boss has told them to do even though they may personally believe that it is a stupid policy. Though I have learned to be much calmer and have patience with other customer service folks, it has also made me loose hope in humanity. The people I deal with on a day to day bases is heart breaking. These people are flat out cold hearted and cruel. They don’t seem to understand that I truly want you to shop with us, because I want to get paid. I am not going to do something to intentionally piss you off, but they come in thinking that is my plan at the start of the conversation. Now I always make sure to have a great day to customer service workers I deal with and I always tip, if I cannot afford it then I cannot afford the meal. It is important to be nice to everyone you come in contact with, that simple smile you give them can change their entire day.
