Yes Bern you are totally right in what you say about the main post office. Unless you have a good half hour to waste and feel like standing idle for that time it's definitely a no-go area. The one at the bottom of Whitfield Avenue is good as long as you don't catch the oaps or young mums first thing, or as Jan said, the one at Whitfield is very good, I always use that one too.
I'm trying to work out what dogs and worms have to do with the post office
