Acting manager on duty refuses to serve alcohol

The person claiming to be the manager on duty at news cafe Bedfordview refused to serve alcohol to a group of us due to his excuse being that it's \student hours\" even though we are all of the legal age to consume alcohol. Yet he still refused to serve us alcohol. However we went to another restaurant and they served us alcohol happily. The incident happened at around 15:20 on Tuesday afternoon the 3rd of March 2016 "
