Paperboy, delivered newspapers, usually Sunday's. At one time I employed eight boys, in a large housing scheme, before there were any shops. When the first general store opened, they tried the council, then the police, to get me shut down. As no one was buying papers from them. They were unsuccessful. It was quite a lucrative part time job.
Knockeruppers, I'm 83 and I vaguely remember them in Glasgow. They could rap the ground floor windows and had the pole for the first storey, I don't know how they managed the second and third storeys.
