Man comes in with son at 5:30 and picks a few comics out of the back issue bin and tries to pay for his $3.50 worth of comics with a $100 bill.
Me: "I can't break that right now."
Random Customer: "How late are you open?"
Me: "We close at seven."
Man and son return at 6:45, decides not take the comics he initially put aside, but picks a new pile of books, equalling $23. Pays in quarters and dimes.
Is now cursed.
He will stub his toe every time he leaves a store where he hasn't used exact change.
