I am a long time customer of your brewery having dined at your Kendalll Square establishment for many years going back to 2006. While I have taken a break since 2019 I recently returned to in person dining today. I regret to say my experience was less than satisfactory. I have had more than 90 unique brews up until today. I entered the establishment slightly after 2:00 PM today 9/9/2022. I proceeded to the bar to order a Doctor's Note pilsner. The waiter did not greet himself, tell me his name, or inquire how I was doing. Very nonchalant. I sipped on my beer and when it was time to order my second round Daryl S. was nowhere to be found. I waited nearly 10 minutes at which point I asked a hostess to pour me a teardrop of Pina Colada. That went unanswered. At which point I asked another hostess to pour it which she kindly did. All is well at this point. When Daryl returned he promptly gave me my recipt as if to expect I was leaving; I was not. When I ordered my third beer he said this is your last. Um, excuse me? When I asked why he said, "I am not going to watch you pound beers all afternoon." By the way, I sipped on two beers over 45-50 minutes. This does not qualify as pounding. For the most part he was not at the bar so how could he say I am watching you all afternoon. Note, there were only two other customers at the bar and they had left after one drink when he told me this. After questioning he said all right I'm taking your beer away from you. He quickly snatched it and took it off the bill and would not allow me to order bottles from the cooler. Note, I drove over an hour to get to your facility specifically meant to order many of your expensive brewery specific releases. I asked Daryl if I was impaired. He gave a blank stare and said what part of ordering no more alcohol don't you understand? I said this is no way to treat paying customers who are quiet and accomodating. He proceeded to ask me if you want to buy alcohol there is a liquor store down the street. Are you kidding me? He also aske me what I do for work. What bearing does that have to do with this situation. He insulted my customer service aptitude which is extremely unprofessional. I told him I am a Principal IT Systems Engineer but again this is irrevelant. I left disgusted and very much dismayed at how such as manager can run a brewery. Please speak with him and share my experience. There is no place for such behavior in any customer-centric hospitality business.
