Today, I found out:
Jimmy John's forces employees to sign non-compete clauses
...lest they take a job at Subway. The owner also likes to shoot big-game in Africa as reported here.
Add that to Burger King (leaving the US), White Castle and Chik-Fil-A (homophobia supporters), Yum! foods, Darden restaurants, Papa John's and local shops that have Fox News on their TV screens, and there's really not much left but McDonald's, and McDonald's is probably an oversight on my part.
Who's left?
