I do want to be clear, though, that getting robbed like this has NOT happened to me. I did have to evacuate a convention one year when the fire alarm got pulled, but I brought my money with me. Part of why I did this, however, was because it immediately occurred to me that pulling a fire alarm could be a GREAT cover for robbing an Artist Alley, and that paranoid thought has lived rent-free in the back of my mind for a long time now.
Rock on, guys, and never stop drawing.
