I've had that experience. Also the experience of not being able to carry a monitor to by both to replace one the broke because "only an authorized union person can carry things into the convention center"

I my one experience, they were more than happy to let us breakdown the booths at the end of the show rather than stick around after 5pm on a Friday.

But setting up or carrying things things during the day had to use union people.

>Total scam

Maybe. Maybe not. Maybe the union electrician is there because once upon a time someone setting up a booth daisy chained a bunch of extension cords of small gauge to run lights and demos and started an electrical fire in a crowded convention hall.

You are really stretching here.
