"dude, let's go smoke it up at the dollar theater"

Lately, I have had to ask several teenagers to stop smoking in our parking lot and leave. The most common response I get is, "we are here to see a movie". My most common reply is, "it's 10:30 pm, you already missed the movie". To all you pot heads, please stop coming to a childrens theater to smoke, it already doesn't smell pleasant here and the last thing we need is pot smell.
