I work in a record/comic book store that also sells DVDs. A lot of them. When you are working in the DVD section of the store you get to choose what movies to put on, provided that they are store appropriate (PG-13 and under). I frequently put on How to Train Your Dragon because 1) it’s awesome 2)…
Personally, my Walmart plays Tangled on one of the HDTVs next to the photo lab. If I’m working at night and on a break, I’ll lean on the counter and watch a few minutes of it.
