Thank you.
Seriously, I think a small wood container with a loose top that the glass goes into would avoid the issue of skidding cups and the potential of a glass shard penetrating the shoe’s sole (not that I’ve ever heard of that happening). Of course, that would mean the end of the standard chuppah photo where the chosson’s foot is in midair and the kallah is smiling and cringing / leaning away at the same time.
(good evening, speedy approver)
