One time taking a delivery through a back alley I came across a rat so large I thought it was a small cat. The rat was so fat it waddled side to side. I'll never eat at any of those restaurants anymore.
I used to work security for FDIC. I was once posted in Boston on a 5th floor hallway with a window at one end. I could see rats in the alley below from 5 floors up. They had to be Huge!
