I stood directly in front of the side door with my bike in front of me, leaving perhaps a 1 or 2 foot gap between my bike and the delivery vehicle. I only blocked their typical exit, i.e., the exit bordering the sidewalk. The driver could have walked into traffic. They expect me to go into traffic, so it seems only fair for them to have to exit that way. Funny thing was that the driver seemed uninterested in exiting that way...
As I recall the driver went through the small gap I left, though not without getting fairly irritated.
