Always out of Stock

last night i decided to take my children to McDonald's for supper and they wanted the happy meal as you get a new toy with it, when i paid for it the order was completely wrong, and when asked for the toys, guess what no stock, my point is whenever i go to this particular branch, they always get the order wrong, staff attitudes is disgusting and they never have ice creams or toys, so why advertise it if you dont have the stock? No wonder why i choose to go to Byrger King where you get what you order and they always have stock its disgusting that McDonald's does this
