Things you can't stand ("shared" bike paths etc.)

[Joker]

If you're running a business, you most certainly owe your patrons a reason. It's disrespectful not to give one. No such thing as personal if it's affecting your business. It's not too much to ask that a business owner simply say, "Death in the family" or some other important thing. To leave nothing is flaking off, pretty much by definition.

Nope. You’re acting entitled. Their personal lives are not automatically your business, just because they run a business. Not divulging the details of closing early to you, is not, “by definition” flaking off. Get a grip.

Business owners, just like everyone else, are allowed a modicum of privacy.

“Closed today/early, sorry for the inconvenience.” Is all that’s needed.
