*Whenever there's like a row of 5 people walking at 1mph and you can't pass them.
*Bad @$$ kids!
*Whenever people push their carts aggressively.
*Whenever I go into a grocery store, and all of the lanes are blocked, so I have to walk to the opposite side of the store in order to get in the back.
*Whenever cashiers throw my money back at me.
*Whenever I buy an embarrasing personal item alone, they ask me "Do you want a bag?"
