Last night we made a reservation online to eat at a restaurant we've enjoyed in the past. When we arrived, we were approached by a manager asking if we were related to a particular person, as our last names are the same. We asked why they were asking, and we were informed that the person they were asking about had filed a lawsuit against the owner of their sister restaurant and that they couldn't serve us. Can they do this? We had no knowledge of the lawsuit, and the person they connected us to is an adult child who doesn't live with us and hasn't for 10 years. We have nothing to do with this lawsuit and don't even know what the circumstances are. This really caught us off-guard and embarrassed us.
