McDonald's Bluff sucks

I purchased what I thought was a rolo mcflurry at McDonald's bluff drive through. Straight after, i had to physically go into the McDonald's to purchase another as i had forgotten to order it at the drive through as well. When I ordered the mcflurry at the cashier, I was told that they were out of stock. I then checked the "rolo" mcflurry that i had purchased at the drive through and found that it was only ice cream and chocolate sauce. I was refunded my money but had i not gone into the branch, I would not have known better. This has happened to a friend of mine as well and who knows how many other people. This is extremely unprofessional and is basically theft. I would have paid for a rolo mcflurry for nothing but ice cream and a drop of chocolate sauce. The cashiers name that tried to sell it to me is Khathide L.
