I say 'still', because it is kind of an older generation thing to do. Having not done it before, I gave our postie a box of chocs last Christmas Eve as I work at home and have quite a lot of chats with him. My mum would leave whisky for the milkman, etc, and I think some people used to leave money in the dustbin lids for the bin men. Now wondering if I've started a new tradition and I should get him something this year too.
It's obviously not anything that anyone would get offended by, and no-one's going to say it's a bad idea. Just wondering how many people did it these days.
