This is so terribly sad. My thoughts and prayers go out to the family. And I hope all who were at Biergarten that day and witnessed it are doing OK.
I ate a late lunch there the next day, Friday, Feb 1st and there was absolutely no indication from anyone that they were upset. (which makes me feel all the worse knowing that all the employees were putting on such a brave face for us customers. )
The band did start playing on time (4:45), but I only stayed for the first couple of songs since I'd been there for quite some time and felt guilty tying up a table.
