In no particular order, and a special place in hell for:
Those who can’t park a car between parking lines. It’s really not that hard.
Those who leave their grocery cart sitting in the parking lot. Just put it in a collection area. If you have kids, the store will help you out.
Those who drive at the speed limit in the left hand lane. Pious fucks.
Those who, at a store and with a line of customers behind them, wait until the cashier finalizes the total before reaching into purse/satchel/pocket and pulling out check book.
Those who feel compelled to share their cell phone conversations; particularly in an elevator.
Those who begin a sentence with "With all due respect. . . "
Those who can’t get through airport security efficiently. Thank god I finally have Global Entry.
Those dog owners who can’t be bothered to pick up after their pets.
Those who can’t just split the tab and those who don’t come armed with cash. If your friends fail to acknowledge you ordered only a salad when they had steak, lobster, and Chateau Margaux, they are not your friends. Make it easy for the waiter – you know you are going to dinner, so bring cash and plan on splitting the tab evenly.
Those who respond only to the first question of a multiple question email.
Airplane pack mules – I understand that luggage gets lost and it takes time to wait at baggage check, but really?
Those whose emails are always accompanied by email read receipts.
