Another little trick from Gan. In 74/75 every time you bought an item in either the Main shop or Tuck Shop the total bill always ended with an extra half pence. There were no half pence coins coins on the island so it was rounded UP to the nearest whole pence. Doesn't seem a lot but in the days of Cigarettes 10p, Beer 10p, pop 3p etc and 400 personnel with no where else to buy anything the NAAFI chaps were doing very well out of us!!!!
