Here's one for you. Many times as I sat in fast food drive through lines, I would see rats scurrying back and forth from the bushes to the restaurants. It's inevitable that restaurants, especially fast food establishments, have rodent problems and unless they get inspected, they don't care. You know that vermin's goal is to get to the food in the store rooms. Imagine that storage area teaming with rats and mice and all they leave behind, all over the boxes and bins and bags of food. Don't get me started on the roaches! lol!!
Now, visualize this in your mind whenever you are driving BY those places and go home and make a shake
