That's nasty. However I wouldn't sue the store. if there were no holes in the package you should sue the company that makes the salad because the mose probably got into it before it ever reached the store...

eat crap then

not even sorry ydi

Never again will you want to eat bagged salad

"Organic salad"

You can actually sue under a negligence act.

my grandfather once bought some deli meat at the grocery store that was supposed to be resealable and it wasn't because of where the "tear here" was. he wrote a very polite letter to the company just to make them aware. he never asked for anything (not his money back or a new product for free) and every year on the date of the letter they send him wheels of cheese and an assortment of meats. just something to think about lol

Most likely the mouse snuck into the bag and died without being noticed by anyone until the bag was opened. The store probably knew nothing about it. Still FYL though.

bring the dead mouse to them and sue them
