1. Ball Park Hot-dogs
It is no longer a secret that those who sell hot dogs would never eat them.
The reason is that they know exactly how this food is made. After grilling, hot dogs usually go into the hot dog water. If some of them are not sold, they are put in the fridge in order to be sold the following day. If not sold again, they go back to the fridge another time. Some of the hot dogs may be as old as 5 days or older.
