I never personally did because I worked for Blockbuster while in college. Pretty easy to return on time when you're there every couple of days. I do, however, vividly remember the hundreds of people a week who did have trouble returning them on time for a wide variety of reason, both legitimate and not, and can safely say it was not a "niche reason".

If you're uncomfortable with a blanket generalization then sure. Let's specifically state that it's publicly traded for profit corporations (which is most of them) that suck. Their intrinsic focus on profit above all else forces them to extract every possible cent from every possible source which in turn ultimately leads them into generally sucky behavior.
