Pathetic
There are all kinds of stories that involve people that can’t stomach their food. We’ve read stories about people who hurled their lungs out, people who stuff food into their pockets or handbags for later, and so on. Then we have this guy, who the OP labeled as “cheap,” that took all-you-can-eat to heart.
In fact, he probably ate so much food that some of it went into his heart. It got so bad that the guy had to be rushed away in an ambulance, presumably to get his stomach pumped. We imagine that was what made this dinner outing a special occasion.
