What do you always carry with you?
I always have notepads and writing utensils on me. I never go anywhere without the ability to jot notes. :D
When I worked as a greeter at Computer City, the greeters were supposed to concentrate on greeting people. We weren't allowed to read or play with the computers. And several other greeters got into trouble for letting their attention wander.
I would stand there with my little memo pad jotting away and nobody said boo to me. I guess it looked like I was working. :D
