Line jumping is one of my pet peeves too. Sometimes I speak out, sometimes I do not. It depends on my mood and/or the situation. I haven’t had the experience of a group of people aggressively pushing their way to the front. If I ever did, rather than confronting them and risking an altercation, if there were security personnel close at hand, I’d talk to security about it.
I have, on occasion, firmly, calmly and simply told somebody that the line-up starts behind me.
People who’ve spoken about the stranger who suddenly appears, standing uncomfortably close to them, has been my most common experience with the line-jumper about to take action.
Here’s one example of the sneaky line-jumper in action. Last summer, while in line to buy a train ticket at Amsterdam’s Central Station, I noticed this elderly, haughty looking woman slowly sidling up the line of waiting passengers until she was standing right next to me. Nobody had said anything to her. The couple in front of me moved to the next available ticket counter and as they did so, I could see that the woman next to me was about to move ahead, so I simply said: “I am next in line so you’ll have to wait your turn.”
She said, in perfect English though with a German accent: “I am sorry but I do not understand.” So I just stepped ahead of her and then moved to the wicket when it became open.
You need to use common sense though and be careful. I obviously didn’t feel any personal threat from a haughty looking old German woman.
However, I had just come from London and had read in the news there of a guy, a family man, who had just died after he had, according to witnesses, politely confronted a woman who’d stepped in front of him at a grocery check-out counter. She reportedly glared at him, swore and called him down, left, and then returned only a couple of minutes later with her boyfriend who then, without warning, sucker-punched the guy. The victim went down and struck his temple on the concrete floor, dying on the spot.
There are nutters out there on crack or with serious anger issues who are ready to blow off at the least provocation so one always must exercise one’s judgement. Engaging the support of others, if you are alone, is always a good idea.
