A woman high on alcohol and butane gas launched a series of attacks on terrified members of staff at a pub, threatening to kill one of them with a meat fork.
Lisa Sehra also bit and kicked employees at The Victoria Suite in Smethwick because she 'harboured resentment' against at least one of them, a court heard.
Sehra was sentenced to two years in prison when she appeared at Wolverhampton Crown Court.
The 34-year-old was already banned from the pub in Windmill Lane when staff saw her there sniffing gas and drinking on September 22 last year.
When a member of staff took the gas canister from her, she grabbed him by the shoulders, kicked his leg, scratched him and bit him, breaking the skin.
A second member of staff tried to block Sehra's path on her way out so she dived at him and tried to bite his leg.
A police officer who arrested her nearby said when he found her she was 'extremely drunk, with a can of butane gas in her hand', the court heard.
Only a week later, on September 29, a member of staff at the same pub spotted Sehra approaching with two young males and carrying a kitchen knife with a six-inch blade.
Mr Bernard Linnemann, prosecuting, said the staff member ran behind the bar, which Sehra then jumped up and sat on, still holding the knife and sniffing gas.
He locked himself in the cellar until she had left and she was later arrested, Mr Linnemann said.
On November 25, Sehra, of no fixed address, returned to the pub demanding to see the same member of staff, brandishing a 30 centimetre long meat fork and threatening to kill him, before smashing glasses and a jukebox screen, causing £600 worth of damage.
When police went to arrest her the following day, she lunged at one of the officers, scratching her neck and cutting her tongue, the court heard.
Mr Mukhtiar Ubhi, defending, said his client had been through difficult circumstances,.
He added: "Ms Sehra always expresses genuine remorse for her actions – her actions which she almost always commits under the influence of gas or alcohol."
Sehra pleaded guilty at an earlier hearing to two charges of common assault, one of possessing an offensive weapon, one of possessing a bladed article and one of criminal damage.
Jailing her for two years, Judge John Wait said it was 'plain that you harboured resentment against one of the members of staff at least'.
