FIVE GUYS laughing

My FIVE GUYS meal today, the standard cheeseburger combo. That's diet soda in the cup so anyone who says that I'm not trying looks like a real idiot right now. Also I'm almost certain the last time I got this combo meal I paid $7 dollars.

When the hell did it get to $9? The cashier was laughing as I handed her my 10 spot. And they didn't put the mushrooms on it like I ordered.
