Standing on the door when it's cold, wet, miserable and people with no coats whining at you because they're... cold...
My 'party trick' when I worked on the doors was to ask the customers who looked too young to give me their birth-date - backwards.
Or I'd ask them their horoscope sign - ask the year of their birth... anything to catch them off balance.
One guy was so confuddled that he gave me 'his' birth year and I immediately told him: "That makes you 47. Off you go."
Haha that's clever. I remember my mom telling me a story about when she was younger and worked in a bar. One night someone had tried to get in using my moms stolen ID haha. Not only did the girl not get into the bar, she was detained for possession of stolen property. What are the odds!
Hahaha! Awesome!
