One time at the store the line was long. About five people in front of me a guy with a case of beer motions to get in front of some guy, the guy says sure. I was in a mood and said, " hey, maybe you don't mind but the rest of us back here do, since your not in a hurry and you let this guy cut in line, maybe you should go to the back!!" Surprisingly I got a few "yeah, that's right" from the people behind me. The guy with the beer said thank anyway and went to the back of the line.
