I had a similar experience in Zurich. It was at the main
railway station downtown. While I was waiting in line with a couple dozen people in the tourist info office, several men/women pushed/shoved and got to the front of the line. People waiting in line didn't make any verbal complaints, but looked at the tourist office agents.... what really surprised us was when the agents said "next" the line cutters went up and the agents didn't even seem to care... then some of the people started a shouting match with the line cutters and the agents....

However, I have also seen a lot of line-cutting in the USA. Mostly it was in fast food restaurants in Washington, DC. One example is the Wendy's near the XM Radio headquarter on New York Avenue. People there don't seem to care about waiting in line.... and since I was the only non-African Americans theres, I chickened out and said not a word. (it was 2AM and the other patrons were all ganster-wannabe types, and even they didn't do a thing about a bunch of other patrons who cut in line...)
