I simply cannot imagine that this was anything but a horrible autocorrupt:
The Local 12 Plumbers and Gasfitters Union is apologizing for a text message about Juneteenth that was sent to 2,000 members.
“The Federal Juneteenth Holiday, June 19th falls on a Sunday this year and is melon Monday, June 20th. It is an optional Holiday for Local 12 Members. Any Member who wishes to take Monday, June 20th, may take the day off,” it said.
I hope you have a good Juneteenth (observed).
