I've only been deducted for concrete in some pipes and when I bought a bunch of school desks. Took in 1 load of desks then the next we took another and the guy said his boss was b!tching at him so on deductions he wrote 20, not sure if this met pounds or dollars but when we get to the cashier she about hands us the money and were like wait we have a deduction. Shes like "I didn't see that"
