I went to the doctor today. Guess what? She's pretty sure I have an ulcer. I need to do more tests though.
Yes, the customers have driven this 18 to have an ulcer. It's not like my job itself is stressful. In the words of Randal, "This job would be great if it wasn't for the fucking customers."
Like the woman who responded to my "Hello" by pointing of the basket of groceries she placed on the belt. And throwing her money at me.
