I didn't think of it that way, but you're 100% right, it definitely wasn't part of the job decision. Our team is very close-knit (besides McGoo), and we would always buy each other food on breaks, give each other rides, etc. If McGoo declined in a respectful way, my boss wouldn't have had a problem. I didn't mention this in the story but McGoo had logged many complaints with my boss (such as the one with me commenting on pregnancy weight) about her fellow employees, all in the vein of "so-and-so offended me" and "what's-her-name is my superior and asked me to do something which I found unreasonable even though it is part of my job requirement!". So I think it was the above coupled with the fact that she answered my boss rudely in front of the high schooler in need of help, when she could have declined pleasantly.
