Decided to host our team social at RSB, close and convenient to our office. We had made a reservation on game night for 3:30 pm and was never told about the 2 hour seating max. Fair enough, it's game night. When checking in for our reservation, the hostesses seemed as if they were annoyed we showed up on time for our reservation. The bar was EMPTY and they struggled to place us all together at a table. Seems they don't plan out their reservations properly.... Regardless of the minor annoyances by the staff, we managed to turn it around and celebrate with the team over some drinks and apps. My coworker is allergic to alcohol (not a preference, allergic!) and told the server and continued to order a MOCKTAIL off the MOCKTAIL menu (ginger ale and lemonade). After the second mocktail, she started to feel flushed. She paid no attention and drank some water and headed out (while this is happening the server and manager were very rude about forcing us to leave since we reached our limit...we JUST paid the bill and were finishing up drinks. The manager even stood by us and watched us CHUG our drinks as if we were in trouble or something). Fast forward to 15 minutes after my coworker leaves. She gets sick on the street, the office and starts breaking out in hives (which happens if she drinks even a spot of alcohol) and ends up going to the hospital by ambulance. We go back the following day to notify the manager of our concern of not acknowledging the allergy and wanted some sort of accountability (reimbursement would be great but trust me none of us need a free meal from RSB of all places..). The manager immediately started to blame my coworker saying she must've DRANK all day before and found it not fair that we ASSUMED it was the mocktail. WE assured him that we all had the same meals all day and night aside from our drinks. NO APOLOGY and completely was on the defense. It is concerning that the manager had no remorse or concern for what had happened. He just assumed we were here for a free meal reimbursement. Completely concerning in my opinion especially for an establishment of that size. Someone on here said it was run by amateurs and I couldn't agree more. Needless to say, was considering hosting a client event there in the New Year...will not be.
