Radio presenter Becky Measures’ venture in to the pub trade fell foul of the law after just nine days.
But the Peak FM presenter is now calling on drinkers to carry I.D and understand the pressures facing the town’s landlords.
The radio presenter opened for business at the Royal Oak in Chatsworth Road in May, but was caught committing two offences during a ‘sting’ operation by trading standards officers and police a few days later.
A volunteer, aged 16, was sold two bottles of beer during a test purchase, Chesterfield magistrates heard.
She also staged a rock band gig without employing door staff - a breach of her licence conditions.
The 30-year-old, of Parkside View, Upper Newbold, pleaded guilty to allowing live entertainment in breach of a licence by not employing door staff and selling alcohol to a person aged under 18 on May 26.
Presiding magistrate David Sobczak gave her a six-month conditional discharge, with £85 costs.
Following the hearing on September 5, Becky Measures told the Derbyshire Times she was new to the business when the sting took place - but has since taken steps to prevent under-age drinking including training staff and putting up posters.
She said: “I feel the public should be made more aware that they must carry I.D as they don’t realise the consequences we pay. The repercussions are massive.
“We could have our licences or premises taken off us. Our livelihoods are on the line.”
The pub now asks all customers who may be under the age of 25 if they have I.D, but Miss Measures said staff had faced abuse.
“If you don’t have I.D we won’t serve you. We have had to turn people away and they have been offended.
“I’m hoping this will highlight the pressures on landlords and to make people aware that it’s not acceptable to go out without I.D.
“It does slow down the job immensely but we have to do it,” she added.
* The operation also caught out Richard Lewis who sold alcohol to a 15-year-old trading standards volunteer at The Wheatsheaf in Newbold Village. He received a six-month conditional discharge, with £85 costs.
