Respect and volition, mainly. If a customer is attempting to leave and you bar their exit, you've demonstrated a willful contempt of their wishes. It causes the customer stress and serves no purpose other than to show them that you can make them do as you please. It's a micro aggression, a type of violence. Imagine a woman trying to leave a man's apartment as he holds the door closed. He reminds her she was the one who came inside and asks again, is she sure there's nothing she wants from him? He keeps his hand there until she says she's sure so she understands, he [i]let[/i] her leave. I'm against either scenario for effectively the same reasons.
