> even had the gall to leave one of their first bottled brews at my great great grandfather's gravesite.
That's a weird thing to do. I can see wanting to steal an established brand because people are attracted to legacy, especially in the case of something like brewing.
But leaving a tribute at his grave is, honestly, just bizarre behavior. Are the obsessed or something? Do they think they have some connection to your family?
One of your family should try to work for them, maybe the company will treat them like the second coming. Or human sacrifice. But hey, worth a shot, right?
