He sat down called me over and said

When a guy, known for causing trouble, walked in.

He sat down, called me over, and said, “Give me a 21-year-old drink, please.”

I nodded, and a moment later, I handed him a drink.

He took a sip, spat it out, and said, “I asked for a 21-year-old drink, and this is 18 years old!

Now give me a new one.”

A bit annoyed, I made him another 21-year-old drink.

Once again, he took a sip, spat it out, and complained, “This is 10 years old! Are you kidding me? I’m not paying. Now get me a 21-year-old drink.”

I was getting frustrated, but I made him another drink. Sure enough, he sipped, spat it out, and started shouting.

This went on for a while until I finally had enough. I handed him another drink and said, “Sir, this one’s on the house, and I can guarantee it’s 21 years old.”

He took a sip, spat it out in disgust, and shouted, “What is this? It tastes like piss!”

I smiled and said, “Well, you asked for a 21-year-old drink, right? I’m 21.”
