Suddenly, a big trouble-making truck driver steps next to him, takes the drink from the guy, and slugs it all down. The poor man starts crying.
"Come on man, I was just joking," says the truck driver. "Here, I'll buy you another drink. I just can't stand to see a man cry."
"No, it's not that," the man replies. "This day is the worst day of my life. First, I fall asleep and I get in late to work. My boss, outraged, fires me. When I leave the building to drive home, I find out my car is stolen! The police say that they can do nothing. I get a cab to return home, and when I exit the cab, I leave my wallet and credit cards there and the cab driver just drives away."
"I go home, and when I get there, I find my wife in bed with the gardener. I leave home, and come to this bar."
"And just when I was thinking about putting an end to my life, you show up and drink my poison."
