Vanishing 52 and 53 to the Witterings

Frequently walk into Chichester as we live alongside the canal and it is our bit of exercise just to have a wander around Bishops Palace Gardens or Priory Park for instance. Walk back along South Street have a look at the display board for times of return buses outside Iceland and, whether it is because they are every 15 minutes and some have been delayed, even though the display board reads, say 2 minutes, it drops out and doesn't turn up. We believe the bus gets turned around at the bus station to save time but it is very frustrating to not know whether there is a bus in "2 minutes" or have to wait for the next bus as we could have been home in that time.
