I've done it myself where I've been full and set the sign to say so, then completely forgot to change it back when people have got off!Took an extremely busy double decker Stagecoach route 3 from Kingsbridge to Dartmouth today, which bizarrely included six dogs. Fortunately they were good boys; everyone in holiday mood. Later the bus I was on passed a 12 from Paignton to Torquay showing Bus Full, when it was nothing like. I wonder if the driver knows the new rules yet?
