Cashier: Look, it's $1.99, okay? Then, I take $1.49, okay. So it's two for a dollar, okay.
Customer: I don't get it, it said it was two for a dollar and you are charging me $1.49.
Cashier: No, no, no, see, it's $1.99, okay. I take out $1.49 okay. See, watch. I scan it and it says $1.99. Then I take out 1.49, see.
Customer: No, I don't see, I don't get why you are charging me $1.49.
Cashier: Ugh… Mary*, come here. (speaks to Mary* in Spanish)
Mary*: When she scans it you don't see the real amount because she isn't finished the transaction yet.
Customer: Then why wasn't she showing me that?
Mary*: She did show you that.
