Discreet Dining Disposal

A character is given food he/she doesn't like or doesn't want to eat for some reason. To avoid consuming it, the character may give the food to the dog to eat or try to throw it in the trash. Sometimes, the dog may outright reject the food, indicating how bad the food is.

During the period of alcohol Prohibition in the US (1920-1933), one of the most effective teams of revenue agents (the guys tasked with enforcing Prohibition) was that of Isidore Einstein and Moe Smith ("Izzy and Moe"), who got up to all kinds of hijinks in the course of doing their job. Eventually, word got out that Izzy kept kosher...so the proprietor of the establishment they were investigating undercover tried to get him to eat a ham sandwich. Moe contrived a distraction, allowing Izzy to quietly dispose of the ham and eat the rest of the sandwich, allowing them to make the bust.
