Burger King Serves Beer?

This story is from a little over ten years ago, so I was either nine or ten. If you read my post "If Someone Tries to Kidnap You, Shout 'Fire,'" then you know that my dad would take us in his 18 wheeler across the eastern US (mostly so he didn't have to unload the truck, because he was a lazy asshole). Anyway, I went with him one summer, and we stopped at a Burger King to eat. I forget where it was, but it was either in Kentucky, Virginia, or West Virginia. I nearly got hit in the parking lot by some douche, which was bad enough, but the real creepy shit went down once we were inside. I ordered a kid's meal with a Dr. Pepper. The cashier was this weird redneck looking dude. I remember taking a sip of my drink a little after sitting down, and it tasting weird, but I had a mouthful of food at the time, so I didn't pay much attention to it. Now, ordinarily, I will CHUG anything caffeinated and/or carbonated, but for some reason, something told me not to this time. After I finished eating, I took another sip- it was DEFINITELY not Dr. Pepper. I told my dad that it didn't taste like it; he tasted it, replied "it's not," then went and yelled at the creepy-looking redneck cashier. The manager fired him on the spot. I later learned in my teenage years that the flavor was that of very cheap beer. So, some creepy redneck, likely a pedophile, tried to get a nine year old boy drunk in a Burger King. (Sorry for the wall of text; I'm having trouble getting things to display correctly.)
