Was this a bit weird?

I had a friend over for lunch on Sunday, hadn't seen her for a while and was looking forward to a catch up and a nice lunch; so just as I was draining off the vegetables there was a banging on my front door, thinking it was a parcel I was expecting I went to open the door. There was a furtive looking man, on crutches with one leg that was a metal prosthetic, he said his car had broken down and could I give him a lift, he didn't say where to, I was a bit stunned a random man knocking on a random door on a Sunday just seemed weird. I said it wasn't really possible and then he said he had tried phoning his daughter but there was no reply, then I said I am sorry I can't help but we are about to have lunch so he said OK I will go and ask my friend up the road?? I told my friend and she reckoned it was a dodgy scam I sort of agree with her, what do you think.
