Do people often sell tickets around the venue before the show?

Not really

You'll only rarely see scalpers, usually easy enough to get tickets ahead of time or at show if you come early.

Yes but the top shows usually sell out befor the band or group arrives

Yes sometime tickets are sold, for promoting parties, this guarantees usually a large crowd

For high demand shows that have sold out or near sell out

Not very often, its a small enough venue that most people that buy tickets plan on using them

Not usually

Yeah from time to time they do. Generally for bigger shows. Wouldnt rely on it because they are expensive.
