The drunkard and the bum

After a night of heavy boozing a man stumbles out of a bar. To sober up a bit he decides to walk home instead of taking a taxi. Soon he finds himself in a dodgy part of town, where he has never been before. Then a homeless person gets in front of him and asks the man for some change.
The man looks at the bum and says: “I bet you’re gonna get beers for that money, aren’t you?”
– Oh no sir, the bum replies with the face of an angel.
“Hmmm, no beers. So you’re gonna get wine then, ey?!”
– No sir, certainly not. I never drink wine.
“Aha, so you’re gonna get hard liquor right?!
– Absolutely not sir. In fact I never touched a drop of alcohol in my entire life.
“In that case, why don’t you come with me to my place”, the man says.
– Oh sir, that would be too much hospitality. I really couldn’t.
The man looks at the bum and replies: “Hospitality? I’m not offering you anything. I just want you to come with me, so I can show my nagging wife what happens to people who don’t drink.”
