Working as a barista at Starbucks allows you to see firsthand the stupidity of some people. Here are the the 6 worst examples, according to someone who worked there (H/T AOL). "Is this drink mine?" Even though the person ordered there drink two seconds ago. "Saying Frappe" Even though that's a drink at McDonald's. "Not saying what size" About a third of all customers don't specify. "Ordering while on your phone" It's just plain rude. "Dumping coffee into the trash" When we ask you if you want room for cream in your coffee, it is so that there is space in the cup to put milk in if you wish. "I want that iced" Unless specified, we will make all beverages hot.
