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.
The source I linked has a similar water content for potato chips, no dispute there. We could say that stack of 500 Benjies would be like eating 2 full bags of potato chips (an amount that would be 2,500+ calories of chips, for scale) with zero water, if you’d prefer to imagine how your digestive system would fare with that instead? Whether fried or baked, all I’m saying is it would be ambitious. :)
For enough money to use as equity on a loan for a house, I’ll gladly suffer for a few days.
