Marvellous little money spinner that, as Ritchie would say.
QF proudly tell us about their fuel hedging and how clever it is, in the annual report, but then apply fuel "surcharges".
A bit like banks charging "fees" to pay staff salaries when they make profits from their business activities like all other types of business.
Maybe we could have supermarkets charging a cashier "fee" to put the groceries through, or service stations charging a "pump fee' for providing those nice shiny pumps. The possibilities are limitless.
