And the bartender shouts at him, “you can not bring that dog in here”.
The man says back, “hey this is my guide dog”.
And the bartender apologises profusely and even buys him a drink on the house.
A little while later another guy comes in with a Chihuahua, but before the guy gets to the bar the first guy spots him and says, “hey buddy the bartender won’t let you bring that dog in here unless you say it’s a guide dog”.
Sure enough when the new guy gets to the bar, the bartender says “you can not bring that dog in here”.
The man says, “but this is my guide dog”.
But the bartender is not having any of it, “They do not have Chihuahuas as guide dogs”.
But the guy, quick as a flash answers back, “What? They gave me a Chihuahua!”
