The Last Ditch Bar, a lesbian bar in Greenfield, Massachusetts, became the subject of viral online controversy after dropping its mandatory face mask requirement for a single night. The incident attracted significant media attention, with the initial social media post garnering over 30 million views and prompting commentary from political figures across the spectrum, including Senator Ted Cruz and coverage from outlets ranging from The Guardian to Fox News.

The bar is known for its extensive house rules, which include mandatory KN95 masks at all times (except whilst eating or drinking), strict verbal consent requirements for any physical contact, anti-discrimination policies, and free entry for people without funds. The venue, which opened last year and has been run by a trio of young founders, has also made headlines for banning law enforcement from the premises and has faced financial difficulties since opening.
