    2nd time in as many visits that they've shorted the amount of food I recieved. Last time they gave me 2 chicken strips instead of 4. This time they gave me 4 nuggets instead of 10. Either a waste of money, or a waste of time having to go back and get your order fixed.

    If anyone goes to McD’s for monopoly, do NOT buy the Sausage McMuffin. The Union Square store refuses to give game pieces for it even if the app says so. I have sent corporate a complaint. There should at least be a sign in the store, but there isn’t. It’s very shady.
