Surely one of the basic rules that defines humankind is: He/she who makes a fast-food run is entitled on the drive home to any french fries that are loose in the sack. And if a particularly sharp turn results in excessive spillage, that’s hardly the driver’s fault. That’s just physics. And if the person who ends up with no fries has a problem with that, he/she can make the run next time. Doesn’t everyone get that?
