A question to a native speaker of English
• United States
I'd probably just say "Oops, you gave me a bit too much!" while handing the extra back to the cashier. Or maybe "I think you might have miscounted." I can't think of a phrase that would be used offhand like we have if a cashier shortchanges us. @owlwings is really good with questions like this, so perhaps he'll be able to help out here.

I would say; "Excuse me, I think that you gave me too much." There isn't really an equivalent idiom to "short change". Many people would use the phrase "short change" as a verb: e.g. "I'm sorry, I think you have short changed me!"
