I've always assumed that when you're waiting for a bus and your desired bus approaches, you hold your arm out to signal that you want it to stop. Here in Milton Keynes, regardless of how many routes serve your stop, if you don't do that the bus simply won't stop, and it's always been that way. Yet I've been seeing a friend living in Rugby lately, and there literally nobody does it. At first I thought it was just because most of the stops on service 4 are only served by that route, but it even applies to the town centre stops that are served by multiple routes. People just stand there staring into space and the bus dutifully pulls in for them. So if the entire town operates that policy, how do you indicate to the driver if it's not the bus you're waiting for? Are there any other towns that don't do it or was I right to assume it was the normal thing to hold out your arm?
