The stunt backfired when Philip Lawrence took Robert Fitzpatrick to court, arguing that it is illegal to pay off debts higher than £10 with coins. Mr Fitzpatrick, 24, ended up with a £1,118.62 bill after a judge ruled that the delivery was unacceptable.

Mr Fitzpatrick, who did not attend the court hearing, told the Daily Telegraph that he had specifically gone to the bank for the coins. He said: “Of course it’s unusual but it depends how annoyed you are with someone."
