If you repost someones sh*te in another persons envelope they have to foot the postage bill.
True but it does mean you have to spend time opening the cr$p and posting it, we had the same postie for 5 years.
As for tipping your postie, if that means no junk mail and him signing your recorded mail and leavin special deliveries with the neighbours saving you a trip to post office in town where its impossible to park due to tourists, well I am
more than happy to drop him £25 in a christmas card each year
