Would you Like Splooge with That?
It looks like a standard Bad Service/Sucky Customer Wank, but it turns into so much more.

In Bad Service, Ravendrexn posts about a bad experience at McDonald's. There's a misunderstanding between himself and the cashier concerning what he ordered so she rolls her eyes and turns away and he proceeds to make himself a sucky customer by cussing her out. The incident alone seems a bit wanky in its own right, but the replies are what seem to rake it all in. Atalantapendrag is not amused but nobody else seems to care what they think as the replies to that comment explodes into all manner of fun wanky tangents, my favorite being atalantapendrag and ashi_moto's throw down on grammar, sheep raping, slash and yaoi. I think you get bonus points for spotting the LJDrama crew in action.
