When I worked in McJail, we once had a promotional chilli burger. God only knows what was in that sauce, but if you breathed at the wrong moment while cleaning the gun you'd quickly find yourself curled up on the floor gasping for air. Each burger was meant to get one shot of the stuff. Some of the hardasses on shift claimed to have eaten one with four, but nobody could remember having seen any of them actually pull it off.
Anyway. Customer comes up to the counter with a mostly-eaten burger - funny how the only ones worth complaining about were always mostly-eaten - and proclaims loudly and profanely that it's not hot enough. Demands a better one. Now.
The customer is always shite, I mean right. Yes sir. Right away sir.
Fourteen shots, we put in that thing. We had to build it in the box to stop everything from sliding off everything else, and fifteen just wouldn't fit. What a mess. We quickly squashed the lid shut, handed it over to Front before it exploded, and then rested our folded arms on the production bin to watch the show.
His first mistake was licking up all the sauce that ran down to his elbows. Bad call. Before he'd even taken a bite his eyes were streaming and his large Sprite was gone. A quarter of the way in, he noticed us watching and grinning - as he rushed to the counter to buy another Sprite. We were still grinning as we gave him three more Sprites after that. To his credit, he finished the damn thing. He left without saying a word (largely because he couldn't), suitably chastened.
Damn, I miss that job sometimes.
