As a ticket seller, you sell tickets for a concert, festival, night club, or other entertainment event or venue. As part of your duties and responsibilities, you may need to sell out each seat for the event, adjust the price for tickets as directed, or help people resolve payment problems. Most ticket sellers work on-site in booths, stalls, or offices, but many ticket sellers help sell tickets over the phone or online. This job often requires you to memorize information about each event, which can include anything from artist showtimes to routes that people should take to reach the venue.
