If they came back, I'd make sure I threw the drink in their face and flick them off with both fingers. At minimum. If I had a gun handy I'd shoot out their tires.
Oh man, that made my month! That guy's reflexes were pretty awesome. There was like .2 seconds between girl getting smacked to douchebag getting pounded on. That guy is a champ. And I should add that ordering a drink and throwing it at the drive-thru employee is extremely lame and stupid. Now, driving through a drive-thru naked with three naked friends is gold. And nobody gets hurt! Except for fast food employees not being able to form un-phallic mental pictures for awhile.
I wish we could do that when customers are rude for no reason, or on their cellphone the entire time. Especially when they're on their cellphone.
I was only kidding. Though I agree that it is inappropriate behavior, but funny is still funny, and some of those videos are damn funny if not just for the stupidity of the kids themselves.
I actually saw a video of one of these "pranks" not too long ago where the driver did the whole "Fire in the hole!" thing and threw the drink drenching the window clerk, but stepped on the gas too hard or something and stalled the car. So the window clerk grabbed another soda off the soda machine (presumably for the next car in line) and dumped it into the drivers lap. Obscentities were exchanged, it was funny as hell. Dammit I wish I could find that video again. *EDIT* Ok... tried a search on YouTube... Found it, or what was it. It was called "Fire in the Hole... gone wrong" but it has been removed for violation of terms of use. I'm hoping the guy reposts it at some point.
