Recently: $9.19 little cheeseburger, $5.09 little fries, $3.39 regular drink. $19.24 total after taxes. But the reimbursement is still a mere $15.45. That means $3.79 of pay was lost to this shop. (Fortunately it was bonused.)
I've wondered about their criteria for increasing the reimbursement, since they have done so over the years.
