A restaurant chain that was serving beer in glasses too small to contain a pint has had them seized by officials.
Birmingham Trading Standards launched an investigation after a "significant complaint" and found the glasses were 8.1ml too shallow.
The action resulted in 41 glasses being removed from two bars in the city and a nationwide recall of the brand of glass following.
The restaurant chain in question has not been named because it was not prosecuted.
A Birmingham City Council regulation and enforcement report on the incident, which took place in November last year, reads "It was referred to the relevant body to action and an audit was carried out.
"The supplier and retailer took corrective action to remove all the glassware from use and supply with immediate effect."
Labour councillor Mile Leddy, a member of the Licensing and Public Protection committee, told the BBC: "To come between a man and his pint of beer is one thing, but to come between a man and his short pint of beer is another.
"I commend the department for finding that a number of pint glasses had been made too small, and therefore short measures were being made at certain licensed premises and the way that they instituted, not just a recall from Birmingham bars, but nationally as well."
