"When you jump up as I approach the exhibit, I feel like raw meat spied by an animal who has not eaten in a month.  Please stay standing"

"I don't want to feel tied to the exhibit for a 20-minute presentation.  Allow me to look around, pick up materials, read your literature and look at your newest products first."

"Don't launch into the sales pitch as soon as I walk into the exhibit.  I may be a long-term advocate, familiar with your products and services.  Do some initial assessment first."

"Rethink sign in sheets.  I am uncomfortable about writing my name and address, as I may not want you showing up on my doorstep."

"Provide enough space so I can gather materials and look at products without having to ask you to move."
