After an unfortunate experience at Vom Fass (see my original review), I had a couple of exchanges with the owner, who was sincerely interested in improving the experience.
I returned to Vom Fass this past week, and was greeted upon arrival by TWO separate staff members, and was assisted by Mary, who did a fabulous job of guiding my vinegar-buying experience. I didn't tell any of the staff about my previous trip while I was shopping, because that would have been weird and uncomfortable, but I did mention it as I was checking out.
I'm very satisfied with my purchases, and will enjoy returning to Vom Fass. Thanks for taking the customer service concerns seriously.
