<human>: So I had been waiting in a particularly long line at the University convenience store and after a while I'm finally about 2 people away from checking out. Some guy walks to the sandwich stand directly next to me then proceeds to say: "I have class in a minute could you purchase this and then I'll give you cash." I respond by saying, "I think you should ask all of the other people waiting in line," (gesturing to at least 25 people behind me). Guy in front of me says, "Here, I'll do it." 

My thought simply was that this is a university and we all are here for class. You are not special because you have a class at the same time as the guy in the front of the line.

Can you summarize the given text in a few sentences?
<bot>: I'm pissed because a good deed to the many got pissed away for a good deed to an asshole. Am I wrong?
