A man caused a fracas at both the Job Centre and the probation office in Fleetwood when he shouted and swore at staff.
Paul Hadgraft, 31, of Pharos Street, Fleetwood, pleaded guilty to two offences of using threatening words and behaviour.
He was bailed for sentence at Preston Crown Court on January 2 by Blackpool magistrates.
Elliott Taylforth, prosecuting, said Hadgraft went into the Job Centre on Kemp street on May 31 about 11am.
He was verbally aggressive to staff and threatened to smash the place up.
He then went straight to the probation office and became aggressive when told his probation officer was not in.
Staff tried to calm him down but he continued shouting and swearing.
When interviewed Hadgraft told police he was upset because he had not received any benefits.
He added that he would not have caused any damage.
Patrick Nelligan, defending, said his client would have to be sentenced at crown court as he was already on a suspended prison sentence.
