Unsatisfied customer

My friend and I went to hungry lion Park station for their after 5pm special to our surprise we arrived it was closed. This was at 6:05 their website shows that they close at 7pm. We asked the staff if it's already closed and they were so rude, they said " can't you see that we are closed". I think this is incredibly unprofessional because it's false advertising as they put up a special for after 5pm but they literally close an hour later.
