I don't normally pick people up, but he looked a bit desperate, so I did. He did not look like a doctor though, so after a while I asked him what was in the enormous bag, which he had put on the back seat. He replied,
"I don't mean to be rude, but that is none of your business."
Well we drove along for a bit and the atmosphere was a bit strange, so to break the ice, I said -
"I did not mean to be rude either, but that is a hell of a bag and I was only trying to make conversation with you by asking you what was in it." He was beginning to piss me off. He answered,
"Look mate, I told you. What is in this bag is none of your fucking business."
That was enough for me. I pulled over, went to his side of the car and opened the door, ordering him to get out, which he did. I then pulled away at great speed, glad to be rid of him.
When I got to where I was going, I found he had left the bag on the back seat, so he could have told me what was in it in the first place!
