You would think that I asked a customer if they wanted me to kill their puppy. It is just a question. One I have to ask in order to know what to put your groceries in. Trust me I have heard every reason not to use one bag one way or another. I didn't ask for your 30 minute lecture. I am doing my job. Thanks to you the customer behind you had to wait and eventually created a long line. This happens to me several times a day. I am suppose to ask every customer in case they are a mystery shopper.
