I used to work as a line stander on Capitol Hill in DC. You get paid to stand in line for lobbyists for hearings and committees. Many times your there a day before and camping out overnight with all the other line standers. It’s like an old school concert ticket environment, if you ever camped out for concert tickets back in the day.
Actually the lobbyist are the ones that do most of the hiring for that position. I worked for the Dutko group at the time, before that I was a bike messenger and they get those jobs all the time.
