Lack of service for a person with a disability. Asked to leave! A disgrace! I have never been so poorly treated by a public establishment in my life. I have disabilities and use a cane, so it is obvious that I need a seat. I realize that the place is crowded. I was there as a guest of a band. After 10 minutes of trying to flag down a person to ask for a table or bar stool, I had to tap a person. I was told by 2 people to leave and come back because they wouldn't be on until later and try and get one then. I mentioned the ADA and reasonable accommodation, and could a gentleman at the bar please give up a seat. When I said that I am a paying customer like everyone else, so could someone please give up a seat. I got smirked at. The post had said 9 on FB. The first person said, "Well what kind of friends do you have if they didn't tell you they aren't going on until later?" So I went outside in the freezing, windy cold and sat in the window. I asked a friend of the band to please text me when she got there to see if maybe she would get me a seat, hoping that she and the band members would realize that I have a cane and would need a seat. I told her I was sitting outside on the window sill and would be wandering Mass Ave to look for a place to eat. After almost an hour, my knees were swollen and bruised. I went back. I had to explain the same story to the bouncer. I told him I would gladly buy a meal, etc. But the ADA requires reasonable accommodation. The bouncer told me I should go to another establishment to eat. I told him I had tried, but everything was closed. And I was there to see a particular band - one of three - that was supposed to play. I was insulted. Then I saw my friend and someone else got seated first while I was not seated, standing on one leg and leaning against a wall, in obvious pain. I apologize for getting angry, but I thought the courteous thing to do would have been to offer me a seat, seeing that by that time I was in obvious distress. "Well, there's no seats!," one of them said. At that point, I took an Uber home. Patrons were laughing. I felt disgraced. I have taken the issue up by other means. But I suffered an injury and now have to go to physical therapy.I think customer service - to everyone - should be a priority - to ALL customers. And I shouldn't be looked down upon because I use a cane. Any other place I have gone to had made sure I am seated. Usually the band and/or the staff see to that and thank me for coming. I am a professional writer. I also write music reviews for a magazine. What if it had been that night?
