Businesses better get priority; I don't want to have to sit and wait in an empty building for hours after closing. That would not be ideal.
Does your business get regular FedEx shipments? What time do they usually show up? Odds are, if you do get regular shipments, the iPad will be on it. The business I work for gets two FedEx shipments a day: one at 10am, and one at 3:45pm. Wish I'd of thought of having mine shipped there instead of my house.
Worst case scenerio, you have to park outside of the place for a few hours. Still beats the heck out of waiting in line, with a chance of not getting one at all. I doubt it'll come to you waiting though.
