Told to leave and not come back

Me and friends were sitting at the four sisters pub and grill on October 20 2015 they were drink and I was not they got loud yet I stayed quite she kept yelling at them in front of everyone and then we left. I came back on October 21 2015 alone she came and spoke to me and asked me to leave and not come back. Yet she tolerates every other drunk person in this restaurant. I personally think she should be closed down
