In the town I live in now, there is no longer a Jack in the Box after some kids from other cities died from food poisoning there.

"...January 1993 outbreak that sickened several hundred people and killed three children from Washington state. "
Recently my girlfriend wanted to go to Dairy Queen to get some ice cream. My girlfriend also got a chicken sandwich which had a lot of fat on it. I got a double bacon cheeseburger and the meat was terrible. It was dry and chewy. Tasted like an old shoe. I asked for a replacement and it was the same. The manager told me they were required to 'fully cook' their hamburgers now. Uh.... Suffice to say, I won't be going back there anytime soon. My girlfriend mirrors my sentiment.
