Most exhibitors will welcome this approach and be prepared to work with you without interruption. Scheduling meals with suppliers is appreciated as it gives booth staff an opportunity to take a break. Visit the entire show. Trade shows allow you to discover new products and services. Don't deprive yourself and your company of the opportunity to uncover unique products and services.
Profits hide in unusual places.
Be open to new ideas. Use the opportunity to interact with companies you ordinarily would not see. Walk the show quickly noting those companies that you want to get literature from later. If you stop to take literature, you will most likely get caught up in conversation and won't get through the entire show. Review literature and return for discussions with those companies that interest you.
