I think it does come back to you via a long route normally, but sometimes it is quicker.
My car had a problem so I was getting a taxi, there was a petrol strike on but I knew a garage that had fuel so told the driver.
I went to get a cab home and it was the same driver, he now had a full tank of petrol so didn't charge me for the return journey.
I try to complement people, if I see someone in a nice dress I will tell them it looks good.
Sometimes you have no idea how much words can harm but also heel and be positive.
I was in another taxi a couple of years ago, we were chatting about the heat and he was telling me he'd been to Saudi with his family, I put two and two together and when I was paying I said, "I suppose I should say thank you Haji", he actually held my hand as he took the money and said it meant a lot to him, particularly when it was someone who was not muslim. I thought he was about to cry.
I've given lifts to strangers a couple of times, one was a teenage boy, I'll admit I had a look at his shopping trolly, he'd asked to borrow my phone because his cab had not turned up.
Another time it was a young mum with three children, she had obviously shared the shopping out to carry it home, her youngest had cornflakes which are not heavy but he was so small he was holding the bag up to his nose.
My dad got a train and then a cab to a wedding, once he got to the wedding he realised he had left his wallet behind, 1/2 an hour later the driver turned up at the wedding venue with the wallet.
