Who goes with Armpit to meet X-Ray, and why does Armpit refuse to sell any tickets to the white guys the first time Armpit and X-ray meet up with them?

Ginny, impressed and excited about how much money Armpit stands to make, accompanies him to his meeting with X-Ray to collect the money. X-Ray, however, tells Armpit that the guys wanting to buy the tickets brought a check, which X-Ray refused, making arrangements to meet them later in a public parking lot.
