Two guys are walking down the road with their dogs,
one guy has a doberman and the other has a chihuahua, when they come across a restaurant.
They want to go in but there’s a sign on the door that says “no pets allowed – service dogs only”.
The guy with the doberman says, “don’t worry I got this.”
He proceeds to put on a dark pair of sunglasses and walks inside.
The manager comes up to him and says, “sir, you can’t have your dog in here.”
The man replies, you don’t understand, this is my seeing guide dog.”
Skeptical, the manager asks, “your guide dog is a doberman?”
The man replies, “you see, a doberman helps protect me against burglars.”
The manager lets him through.
The chihuahua guy sees this and puts on a pair of dark sunglasses and walks inside.
The manager approaches him and says, “sir, you can’t bring your dog in here.”
