It's so true. Everytime a persian comes into the store that can barely speak English, I know I'm in for a world of hurt when it comes time to check out. Although it's how it works in their homeland, they should know after living here for years that a transaction is a goddamn transaction and shit's priced as marked here in the states. Every time like fucking clockwork, they come to the counter with an item and the first thing out of their mouth is "This best price? Can you give some discount?"
Fuck them. I've never asked for a discount on anything other than a medical bill in my life.
