We just stopped in to get my boyfriend a beer and both of us some food. We asked the waiter if they served any beverages other than beer. I explained beer upsets my stomach and was hoping to get something easier to drink. He suggested a half wine/beer mix. I said "I wonder if that will upset my stomach" he replies "I'm not a doctor and can't tell you that" straight faced. It was stated in a very rude tone. He said we are a brewery we do not serve anything but beer. I get that it will be mostly beer however lots of breweries offer other beverages as they know not everyone coming in for food wants beer.

His tone and attitude turned is off immediately and we chose to leave. Didn't even try the beer or food.

My advice - put as much effort into training the staff as you do making beer.
