You know it's a bank holiday weekend when a photograph of an MP drinking a Mojito-in-a-tin on the London Overground makes front page news.
Transport for London (TfL) banned passengers from consuming alcohol (and from carrying open cans of alcohol) on its trains and buses in 2008. "Anyone caught consuming alcohol may be prosecuted," TfL's Conditions of Carriage state.
Diane Abbott, Labour's Shadow Home Secretary, knows this, and swiftly apologised after she was photographed sipping from an M&S Mojito can as she travelled home to her north-east London constituency earlier this week.
So on Twitter, Abbott's "tube Mojito" has actually provoked some pretty appreciative tweets. The hashtag #CansForDiane has even been trending as people crack open gin-in-a-tins and mojito cans in her honour.
And let's not forget that Abbott, who in 1987 became the UK's first ever black female MP, has long been a target for sickening racist and sexist abuse.
Last November, she revealed that she receives threats of “rape and violence on a daily basis” simply for doing her incredibly stressful job.
So if she fancies a few swigs of mojito on the way home, well, who are any of us to judge?
