#5 of the the ten "weirdest taboos in Sweden" is a deal breaker for me. I get LIVID when I am in Sweden and someone tries to cut the line (that's what we call it in the States). It's part of the American culture too. Believe me, I work at schools and no where else is the line more closely monitored by guards and "inmates" (AKA children) than there. :-) "She cut the line!", "He cut!" These cries bring a shiver to my spine. Ugh! And it's even more infuriating when grown-ups try that ****. So just don't and definitely not in Sweden where they will appear to be casually queuing up but actually everyone is zealously guarding their spot in line.
