Please fire me. My boss complains to me regularly about how the customers in the grocery store I work at are cold because the automatic doors get jammed open. I work outside pushing shopping carts in freezing temperatures, rain, snow, or whatever other weather there might be, and when I go in the store I start to sweat from the heat. First, I don’t know how to fix the doors, so I don’t know what she expects me to do about it. Second, don’t these people understand that it’s cold in the winter? They should have dressed warmer than shorts and a t-shirt.
