Man, that's unbelievable.
Once someone has smoked in a vehicle it can
never be the same. Its like rape, only worse. Everyone who gets into your truck will know. It'll start getting those
looks. Friends will avoid riding with you.
Even if they de-odorize it, you'll always
think you smell smoke, so they definitely should replace your truck. The offending employee and those who covered up should be fired, and if they have children, reported to Protective Services as abusers. Maybe sent to GITMO. You should get a lawyer too...I smell big emotional distress money. We can only imagine how truly violated you must feel. But just remember, we're all behind you and we'll help you get through this.
