A bad day joke

A guy was looking at his drink, deep in thought. He was like that for half of an hour.
Then, a big mischievious truck driver steps next to him, snatched the drink from the guy, and drank it all down. The poor guy starts sobbing.
The truck driver teased, "Aww... come on man, I was just joking. Here, I'll buy you another drink. I just can't stand to see a man cry."
The guy replies,"No, it's not that. Today is the worst day of my life. First, I fall asleep and I go late to my office. My boss was boiling mad and fired me. When I leave the building to my car, I found out that it was stolen. The police said that they cannot do anything. I got a cab to return home, and when I left it, I remembered that I left my wallet and handphone there. The cab driver just drove away. I went home, and when I got there, I found my wife in bed with the gardener. I ran away and came here. And just when I was thinking about ending my life, you showed up and drank my poison."
