Twenty Players Weights for the headmaster

I left Cranbourne Road, later named Kingsthorne School in 1957, my last teacher was Mr Ledger from class 4a … Mr Hawkins was the headmaster who left and Mr Worralll then became headmaster and Mr Martin was is deputy. Can recall being called out of the class by Mr Worrall to go to paper shop on Kingstanding Road to fetch him a packet of Players Weights cigarettes, somehow dont think that would be allowed now?
