Never mind request stops, on the buses I've had more than one incident where the driver has failed to stop at a compulsory stop after either myself or some other passenger has got up and stood by the exit door on the approach to said stop. When challenged as to why they didn't stop the usual response is "You should have rung the bell". They don't like it when I've replied that "I don't have to because it's a compulsory stop and you have to stop there".
Couple of weeks ago myself and a couple of other people clearly put our hand out to stop a bus that was due to stop at a particular stop. Bizarrely the driver just made some gesture and continued driving. The bus was not full - this was about 1pm midweek - and it was definitely the correct (urban) stop for that service. And the following bus on the route did stop. No idea what that was about...
