One of the most unrealistic scenes of all time

I find this film entertaining and i love Charley B but i gotta say the scene in which Charley B walks into that store with no money and asks to make an out of state call is bull****. Ok the store owner grants Charley B the call. I buy that. I reckon a kind hearted person would of helped him out. Then Charley B asks to make a second out of state call and again the store owner obliges. So far i'm cool with all of that but this is the kicker for me....As Charley B goes to dial the number for the second phone call he turns to the store owner and says...and chuck in a couple bottles of beer? The store owner nods her head and says Okay. Who in there right mind would say okay to that? I'm sorry but if that was my store i would of told Charley B to *beep* off. I know later on Charley B gets that mob guy's girlfriend to drop off some money to the store owner but in the establishing scene Charley B never says once about paying the store owner back, thus making it one of the most unrealistic scenes of all time.
