All in one sitting. You get one condiment of choice, and a large glass of water. Bills can be torn up before consumption but nothing is stopping you from housing full Benjamins and digging for gold in the bathroom later. I think I could probably eat at least 10, and I would pick BBQ sauce.
Do I have to keep them down? Because if I can rip and salt them before, I can eat a lot, but I’m going to need my stomach pumped. Even if there isnt something toxic in there, they will cause a bowel obstruction.
Speaking from real world experience, I can consume around 1 kilogram relatively comfortably, with normal water consumption. I might be able to push that to 1.1kg with minimal water, but I wouldn’t if yakking means I lose it all.
