This must be a workshop for golden oldies under the supervision of the gentleman sitting at the desk. Actually that is my dad and upon a visit to London he was in charge of calling the lotto numbers for his golden oldie ladies in the local senior club. He had a loud clear voice so was elected to be the chief caller at the sessions. He was surrounded by his harem of grey haired groupies and would call out the numbers. It was quite an exciting afternoon, especially if one of the ladies called out for a completed card and had made a mistake. That was a so-called lulu and caused much consternation amongst the members. However there were no fights or arguments and everyone remained calm. There was no ambulance waiting outside in case of injuries.
