Stop being mechanical. I know it gets old all day saying the same thing, answering the same questions. It sucks. But please remember one thing. You filled out the application. You said I would like to work here. When they told you the expectations of the job you said sign me up. Sounds great. Now flash forward to today. Been on the job a while and it's getting old doing the same thing every day all day. Don't get attitude when you are asked a simple question. You may have just said it but I just walked up as you finished. Just smile and answer the question. You don't get attitude on payday when you get your check so don't get attitude with your customers. That's right your customers. And if you want to really deep dive I'm a taxpayer so I am the one paying your wage.
