if they won't accept it, or question it, tell them you want to speak with the manager, this is a corporate coupon and you will raise hell if they want to give you any problems, any manager in their right mind will be more than glade to take a corporate coupon to keep a customer happy, tell them, they messed up your order over a year ago and you just never come back yet.
yeah if you think your mcdonalds is something special then please don't bid on or buy this one, i want to sell it to someone with confidence. being a manager i would always take it at all costs but i'm no special mcdonalds store either i'm just like the thousands of others
i understand that but it only helps you actually calling out a manager to help show a worker how to do their job right so your next experience will only be better.
