Once you are all set up, take a look at your table/booth from the side(s) your customer sees. Looking at everything through the eyes of the customer, you might notice something that you wouldn't from your selling position. I do shows with a friend & one morning when everything that could go wrong, did, we were hurrying to set up & she placed all of her labels on one side of the table facing US. It got busy very fast & we didn't realize the mistake until a customer mentioned it about 30 mins into the show. She has been doing shows for 16 yrs and never made this mistake before but was just rattled over the events of the morning & having to hurry.
