Whataburger complaint: Unprofessional and Childish behavior.

A little before 8 am local time I walked up to the counter. The gentleman in the supervisor shirt, asked, What can we make for you, Boss? I wasn’t sure I heard him right, so I asked Did you call me Boss?. He indicated he had and I said, I’m not your Boss, that is slang, and that is unprofessional I started to give my order, and he backs away from the counter and says I don’t need to take your order. I stood there for rather a long time, an employee saw that two people had come up behind me and ask retoracly Who’s tsking orders. The supervisor came back up and told me I told you I didn’t need to take your otder. i got out of the way when he asked the person behind me How can I help you? (He did not call them Boss) After he helpped everybodyelse I moved back to the counter and He told me again I told you I don’t need to take your order. I asked if he could go find somebody else to take my order. He ignored me and did something else looking the other way. I told another worker He’s acting so childish. They ignored me also but my complained is only against the supervisor. Then in a totally unbelievably childish behavior, he whent on the other side of the equipment and peeked at me through a small hole as if he were a 5 or 6 year old. He was talking about me and a second employee had to peek through the hole at me. Oh boy they thought it was so funny. Then finaly a much more mature lady came and took my order. I thanked her and waited for my food to given to me. As the supervisor had shone childish behavior, I did watch him pretty close to make sure I could give the food to my daughter without consern it had been tampered with.I did not see anything out of the usual. I filled up my cups and realized I should have asked for a cup holder. When I adked the girl turned away from me, and I asked out loud Did she really just walk away from me? The girl that took my order said She’s getting it for you. felt bad because I thought the cup holders were under the counter, I didn’t mean to upset her. I apoligized and whent home. So basically the supervisor had caused a tense atmosphere becausewhen I told him he had been unprofessional by using slang. A mature person would have saidOh, I’m sorry. and took my order so I didn’t have to wait a long time watching his childish meltdown.
