Granite City Food & Brewery Tracking Order Status

After many visits to this restaurant my table last PM was treated so poorly it will be our last visit to the establishment. We asked waitress if they could make an apple martini, she said yes. We received a martini glass 1/3 filled with a terrible tasting drink. We told waitress who said she felt they were underfilled as well. Young lady bartender came over and said she made the drinks based on a recipe she read and not many people order them. When I explained we have had them in many places over years and these weren't right she said in an extreme condescending and defiant way "I can't just give you free alcohol. Sorry " (we didn't ask or expect free alcohol) she turned herself around like an angry teenager and huffed away. Everyone at table was shocked at her demeanor. Manager then came and said drinks are half full so will only charge for one. I believe the correct customer service approach would have been a polite, I'm sorry you don't care for them, can I bring you something else or take them off your bill. I was made to feel though like I was looking to scam them out of a drink or get something I didn't deserve. I wasn't. It was a terrible beverage. I would suggest manager and bartender try and drink one themselves as they made it, just not anyone else. So easy to just be nice instead of belittling us.
