My sister worked for a video store in high school (a small chain, now defunct–at least, that particular store is gone now) and she rented just about every kind of movie. Take this opportunity to expand your horizons. If, while cleaning the shelves, you see something that tickles your fancy, go ahead and pick that up for the night.
She told me that the rationale for letting the employees rent for free was so that they would be familiar with the movies so that they could recommend movies to their customers. Of course, her boss wanted them to rent the new releases so that they could push them, but my sister, in good conscience, could not recommend most of the new Hollywood dreck. She raided the foreign and classics sections, small and crappy as they were (if small stores are known for better foriegn and classics sections now, it’s because the ones that didn’t have them didn’t survive. When I discovered anime in the early 90’s, I told her to tell her boss that he should get some anime titles. Nothin’ doin’. Well, look how big anime has become!)
If anything, after you’ve worked there a while, you should rent Clerks. You’ll laugh your ass off.
Actually, in my area, the only small video stores that are left are just fronts for porn rental. A few crappy “regular” videos in the front, while the “little back room” has taken over almost the entire store! You have to go to Blockbuster to get a “normal” movie.
