Assuming there is fire beneath the smoke .....
At 30 years old, he should be pretty well past making significant verbal mistakes. I'm going to hazard a guess that this was not strike one ... for his sake, I hope all of the strikes did not occur during one calendar day. Gigs like his are at least as tough to get as the natural talent he appears to have as a pure driver.
Powerball is pretty big later this week, he may need to throw a $20 at that as part of his "digging out of a deep hole" plan ... it's the only way I'll ever own a pro stock team, so I'll definitely throw a president at it!
Prior to that move, he probably needs to, without describing his actions, publicly admit that he made a huge mistake that he greatly regrets and looks forward to proving it was an aberration of character. He skipped a chance to do this earlier with Bobby, knowing Bobby's character somewhat I'm sure that door will remain open for quiet a while.
Good luck kid, even if you get another ride tomorrow this episode needs to be something that comes to mind often and makes you grimace. A moral compass needs consistent reminders to keep it well aimed.
