A grocery store. A customer with a shopping cart notices someone with a service dog, as the animal is labeled with its coat. The dog is thinking about business.
The shopper with the cart has a tiny devil appear on their left shoulder in a puff of smoke.
To the shopper’s astonishment, the devil jumps up and down with hearts in its eyes, shouting, “Doggy!!! You gotta go pet the doggy!”
The devil points at it excitedly, saying, “A doggy in the store of all places! Wow, what luck!”
Meanwhile, an angel appears on the shopper’s right shoulder. It says sternly, “Do not pet that dog! It’s a service dog, and you shouldn’t pet them while they’re working.” The shopper is bewildered.
The shoulder devil screams in delight, “Oh my gosh a service dog?? Even better!!”
Yanking on the person’s ear, the devil yells after the dog, “Genius dog! Hero dog! Doctorate dog! Can I have your autograph, doggy???”
Caption: “P. S. The feeling is mutual.”
The service dog also has an angel and devil over its shoulders while it’s trying to carry about its business.
The angel dog says, “You must resist! Concentrate on your work!”
The devil dog barks, “Lick that person’s face! Sniff their butt!”
