I had a taxi man drop me home when I had lost my wallet. (Many years ago). He was happy enough for me to post the fare to him...more fool him!!!and so you should apologise. Totally out of order. I have come across many an honest taxi driver and one in particular that springs to mind was when he called me back to the taxi and handed me my purse which contained €125. As in all walks of life there are honest and dishonest.
Only kidding, I did post it.
