Retail jokes
This film is certainly not meant to be a realistic portrayal of work in a retail establishment, but there are a few lines that really nail some of the funnier and more frustrating aspects.
My favorite is this exchange:
Customer:How much is that belt in the window, the one that says 2.95?
Kralik: 2.95.
Customer: Oh, no!
It's even funnier if you listen to it:
