The numbers down the long sides of the ticket show the fare stages on a journey. The conductor had to punch a hole next to the relevant number to show where the passenger had boarded the bus using a special metal clipper. Because of this, conductors – especially women – were often called ‘clippies’. The different colours helped the conductor quickly select the right ticket. At the end of the shift, all the tiny coloured dots clipped from the ticket would be sorted and counted by someone known as a ‘confetti counter’, to make sure the correct fares had been taken and handed over to the bus company.
