McDonald's

Tonight I am recovering from Connor's 5th birthday party and decided to buy the kids McDonald's for dinner. Another thing I missed - the 2 minute walk to McD's when I'm too tired to cook for my children. So I am standing in line watching this young guy place an order when he flipped open his phone. I thought, 'Hmm, a bit rude,' then he said something to the cashier and I thought, 'Okay, maybe someone is texting him their order.' THEN he places the bottom half of his phone on some disk thing in front of the register which then lit up and apparently that paid for his food! George Jetson , your order is ready.
