This person was a 30s something white male who got just about everything wrong and held the line up for 5-10 minutes. Maybe he somehow grew a brain since yesterday and won't get everything wrong again, but I wouldn't bet on it. In fact, I don't think I could have held the line up for that long if I tried even if I was drunk. It was so bad that people were jumping to the other line.
Understood. I doubt he's a freqent traveler, though, or you'd think he'd have the routine--silly as it is--down by now, so punishing him with a trip to the back of the line would have limited value to anyone except those immediately behind him.
