A while back an acquaintance asked me to help shift a table from her flat to ground floor of her towerblock. Why not. It would get my good deed of the day done before lunch. Now, a lot of people would show their appreciation with a five dollar bill - less than the cost of a pint of beer these days. I'd decided to reject the offer. It's not a good deed if you get paid. But there was no offer. I think she'd mentioned I wasn't the first person she'd asked that morning to help move that table. Maybe the others had helped her move tables before.
