They're like heads and tails on the same coin - nailed together but facing in opposite directions and not talking to each other. Or they are round here anyway. When they split some years back RM took their letter box out of the post office on the basis they weren't going to collect the contents. Before the split you bought a stamp, stuck it on your letter and put it in the box next to the counter. Now you have to take it down the road to the RM building before you can post it. RM, of course, don't sell stamps. Thank God for email and a plague on both their houses.
