1 /5 oscar: The sign at the entrance said “walk-ins welcome,” so I went in and waited near the front. Several staff members saw me sitting there, but no one approached. After about 20 minutes, I asked if I could get a seat, and was told there were no available spots for the day. There was no apology or prior notice. It would have been helpful to indicate this clearly at the entrance to avoid confusion. Unfortunately, the experience left a poor impression, and I don’t plan to return.
