Bee: The argument against prepay doesn't stack up to me. Prepay means you have to go into the store before you get petrol, and queue and grab that pie and a v while you wait = Profit...
I would love to know how it is the staffs fault when someone steals petrol otherwise, and is the store owner willing to supply a high powered rifle to their staff to prevent these thefts???
Yes "otherwise" is the consideration in contention. If the situation is "otherwise" then of course the employer has no right to dock pays.
