Well, there are genuine discomforts to experiencing extreme crowding on a regular basis that are not immediately perceptible through the relaxed and leisurely lens of a tourist.

For starters, most shops and restaurants offer things of "tourist quality" at "tourist prices". Getting to work on crowded sidewalks is a real pain, if one is in a hurry. Waiting half an hour in line for a coffee, same problem. Constantly being bombarded with others' mindless happiness while having a mundane and boring day, very annoying... but maybe that one's just me.
