Irritated By Both Left And Right Humor

A customer is watching a video while waiting for his order. My coworker tries three times to get his attention to ask if he wants it for here or to go, but to no avail.

I walk over to him and tap him on his right shoulder, hoping that he will look up and see that my coworker has been trying to get his attention. Instead, he looks over to the left where I have abruptly stopped after I realize it would be more appropriate for me to ask myself, since I am the one who tapped him.

Me: “Would you like your sandwich for here to go, sir?”

Customer: *Clearly irritated* “To go, please.”

At the counter, as he is paying:

Customer: “I’m curious why you tapped me on my right shoulder and then walked over to my left. Were you trying to play a joke on me?”

Me: “No, sir, I was not. I was only trying to get your attention for [Coworker], and I realized after tapping your shoulder that I should have waited there and asked you myself. Sorry if I scared you.”

Customer: “I’m not scared; I’m irritated at you.”

Me: “Oh. Again, I apologize; I really was only trying to get your attention.”

He then spent the next minute ranting to my coworker that I shouldn’t have played that “joke” on him. At that point, I, too, became extremely irritated but I distracted myself with cleaning to avoid any further contact with him. My coworker simply smiled and told him to have a nice day.
