I have never dealt with scalpers before, at any arena or stadium that I have ever been to, but I imagine that there are some that harass a couple of people. My advice would be to ignore what they are saying to you, especially if you already have a ticket. If they continue to try and get closer and closer to you, try to catch security’s attention to have them taken away. You will always be able to know when a scalper is approaching you, because the first thing they say when they come up to you is, “Do You Have a Ticket Sir/Ma’am?” When they do that, just look forward and keep walking!
