Very unprofessional customer relations

experience was atrocious. My family and I numbering five had dinner and drinks and while we were considering the dessert menue, we were asked in front of a full restaurant to get up from our table and move to another table as they wanted to rearrange tables for patrons who had just arrived. My wife and I politely and reservedlyasked for the person in charge so that we could voice our displeasure at the poor customer treatment we were given. The person who informed us that she was a manager was rude and unprofessional and threatened to sue my wife when had taken a photo of our bill so as to have a record of the date and time as well as the unused table we were made to move for. I will never advise or encourage anyone to use this restaurant because the staff are rude and unprofessional and to make matters worse, no senior management or owners of this establishment has made contact to apologise or at the very least explain why we should be happy to be publicly humiliated despite me leaving my contact details for further communication.
