Check the price for overcharging

I just ordered a Whopper meal, straight from the menu. They tried to charge me more than the menu price. Blatant ******ion, hoping customers don't notice the extra couple of bucks. The excuse? The menu price is for sugar-free drinks. If I order an item from the menu in front of me, I expect to get that item, for that price. Not a different item at an inflated price. I will be addressing this further on social media, ensuring that people are made aware of this immoral practice.
