Seems hard to believe as customers generally give Subway employees instructions as to which type of bread they want, the meat, cheese, and assorted condiments (all while watching them prepare) the sandwich!
It would not surprise me if the dead rat in a sandwich turned out to be a hoax or someone put it there looking to sue for a big payday. Several years ago a woman put a human finger in her bowl of chili at Wendy's. There was a huge investigation.
This led to a felony charge of attempted grand larceny against her. Ayala pleaded guilty to the charge in September 2005, and was sentenced to (nine years in prison) on January 18, 2006.
Having said that I did see the video clip you provided which shows a rate munching on cookies in a display case in Subway. Periodically surveillance cameras reveal rodents in various rest
I don't believe this deters most people from going to (their) local one.
Rarely do I go to Subway but if the mood struck I would still go.
