This has all of the effects of tasting food (various moodlets based on
quality and food type) and can also trigger food allergies if you have
them, however it does not consume the food nor give you any nutritional
benefit.
You can buy it from a vendor or sometimes it spawns in maintenance.

## Why It's Good For The Game

The players are constantly clamouring for more additions to our most
loved and useful feature, skill chips.
