You forgot the holograms(aka special lighting tricks)....
If they just had the balls to walk up to the group of really hot girls at the front of the line, they would have realized that they(the girls) weren't real. And that there really wasn't a line of people to get into the booth. There was a line of videogame nerds and geeks that were too afraid to approach the attractive women at the front of the line. All those with the balls to step up, got into the booth.
It was a test, a test to see if you are ready to get off your ass, a test to see if you are ready for the next level. The next level being Interactivity. If you didn't get into the booth... you failed.
