Continuity mistake: When Veronica give Dante the lasagna, Dante syas he will be closing the store, but he doesn't find out that he has to close until the next scene.
Suggested correction: Dante actually says that his boss has not shown up yet. It's already past noon, the time when he expected to leave. He probably suspects that he will be working much later. I've had similar jobs, and it was not surprising if a late manager/co-worker ended up not coming in at all.
Continuity mistake: Dante gets fined for selling the 4 year old girl cigarettes at 4 o'clock. The girl was sold the cigarettes much before even 2 o'clock, before the store was closed for hockey on the roof.

Continuity mistake: The clothes worn by the mother asking for "Happy Scrappy Hero Pup" change.
Factual error: When Dante is fined for selling the cigarettes to a child, the agent tells him that his fine cannot be contested in any court of law. That is not correct because of due process; any citation or fine can be contested in court. Dante could plea for a reduced fine or to have the charges completely dismissed.
Suggested correction: He doesn't say the fine can't be contested. He said the summons can't be contested. A summons means having to appear in court.
