A man with a bad drug habit was given almost £70 a day by his grandmother to fund his habit.
But when David Duffield’s gran put her foot down and refused to give him any more money he became angry and aggressive with her.
Duffield, 27, of Roylen Avenue, Poulton, admitted breach of the peace and was bound over in the sum of £150 for 12 months by Blackpool magistrates.
Sandra Ardern, prosecuting, said Duffield lived with his 80-year-old grandmother who had recently lost her husband.
The prosecutor said: “On December 4 he asked her for money. She became extremely upset and said she would not give him any more.
He became aggressive towards her and the police were called.”
Duffield apologised for his actions.
