I just don't understand people who do that. Apparently a few months ago an older lady was standing in line with her husband and she had an accident. And then changed lines from one register to another and... did it again. Didn't even try to get to the bathroom or go outside or anything. Didn't apologize or say a damn thing. I am so thankful to have missed that because while I'm normally not the confrontational type, I think I would have yelled or something because who does that?
