This one time, in graduate school, a harvester told me that he loved wearing gloves when he picked tomatoes because it kept his hands from getting dirty.

Another time, in graduate school, a greenhouse manager told me he had convinced his boss that food safety was really important and the company invested in installing full restrooms in the greenhouse — and fully stocked a closet with latex gloves.

The manager trained all the employees on why clean hands and gloves were important.

A week after the training session he saw an employee urinating on the outside wall of the restroom.

With his gloves on.

Or maybe gloves are there to protect the food handlers from the food (thanks to Carl Custer for the cartoon).
