Ever notice how the presence of a booth, table, and chair changes prices?

This is something I've noticed for years, and I think it has to be the combination of the three that makes it work. I have no idea why. I know it's not unique to me, I've seen myself and others time and time again pay larger prices for worse quality products just because they were sitting behind a table with a chair, and a little booth.<br><br>As a college student, I sell parking for portraits at football games. I can't sit in a chair, or I'd be fired, but since I'm behind a table with a booth, I charge $10, and get it. I used to work concessions at a minor league baseball team. I would stand behind a small table, and booth, and I charged $5, and got 3 takers per game. However, at a concert I worked, I just had a table, with a 5 gallon bucket. No booth, no chair behind the table. I stood there, and I got 1 person over the course of 4 hours to pay $2.<br><br>Restaurants are more expensive than street vendors, but are a lot more comfortable. However, they don't sell food out of buckets, and no one stands behind the cash register.<br>Does anyone know what this is called? I've been wondering about it for a long time.
