No phones in Superman's Booth

Okay, we all know it is tough to take time out of your busy work schedule to work an event, but taking the cell phones out of the booth really pays off. I'm not saying leave the cell phone in the hotel room because in this day and age, you really do need to be connected to the office and home. I am just suggesting that if you make sure the booth is covered, then step away from the booth and take the call you really will be super human. This will accomplish several things, it makes it easier for you to hear once you leave the show floor, it demonstrates the importance to the caller and it signals event attendees that you are currently unavailable. If you have no one else to staff the booth, you must ignore the call and return it when booth relief is available. It is rare that someone will enter a booth if the staff is engaged in a phone conversation or checking e-mail.
