In the past when I was working for a magician, girls would walk up to me and ask for my number after the show. I would always respond "yeah just ask my wife over there, she can give it to you." Most of them were tourists so it would have been harmless, however I left the decision up to my wife out of respect for her. Most girls would not even try asking my wife but a select few would ask and one seceded in getting my number from my wife. She had moxy.
