I'll take whatever they are giving, if'n it is a load of coins then I just put em all in a plastic coin bag and spend em at the Tesco self-service till.
I once had a bootleg job where the customer paid about 40Euro in coins and topped it off with a 4Euro winning Lotto scratchcard, the coins I spent in Tesco and the scratchcard knocked 4Euro off my next diesel fill-up, but granted I did Block him after that job.
