A man lay across chairs in the middle of a shop after demanding a refund for a tracksuit he had bought.
Kelvin Abram threatened to knock the shop manager out if he did not get one, the court heard.
Abram, 32, of Enfield Road, North Shore, pleaded guilty to using threatening behaviour.
He was given a 12-month conditional discharge and ordered to pay £15 victims’ surcharge by District Judge John Maxwell sitting at Blackpool Magistrates’ Court.
Judge Maxwell described his behaviour as “stupid and pathetic”. Adrian Hollamby, prosecuting, said police were called to Scots Store, on Victoria Road, where Abram was causing a fracas after being refused a refund on May 7.
Officers asked him to leave and he began to, but then turned and said something.
He was told to go away but returned again and made a gesture.
He was then arrested for using threatening behaviour.
