How would you feel like when you are waiting for something in a shop and then someone just walks right to the front and buys their shit and walks off. You'd be fuming, ready to crush the can of coke on the guys face.
It happens here in Turkey, it infuriates me. Cars beep AS SOON as the lights turn green. There's a attitude of impatience which is proper fooking annoying, and they don't shower. But, that's for another ignorant, bigoted time.
