Misapplied

When the manufacturer of a car, truck or "other" item offers a "rebate", who cashes in?  Assuming a new vehicle, we have 2 or 3 questions:

• Does every "dealer" or "sales" individual always remember to "apply" or "inform" the "rebate" for the benefit of the "purchaser".
• Does any "dealer" or "sales" individual ever forget to "redeem" a rebate for their own benefit.
• Is a "misapplied" rebate "mythical" or do they negatively or positively affect an entity's "gross" or "net" income?

Mistakes may or may not be never or often made.  We don't have means to "tally" the numbers.
