A day in the lives of two convenience clerks named Dante and Randal as they annoy customers, discuss movies, and play hockey on the store roof.
 
No review.  Just a quote from the movie.
 
Dante Hicks: I'm not even supposed to be here today!
 
Nuff said.
 
FUN FACT:  Kevin Smith worked in the store where they shot the film. They shot for 21 straight nights. He would clock in at 6am and finish at 11pm. They would then shoot till 4am, after which he would try to grab an hour or two's sleep before getting ready to go back to work.
