I don't think the captains are graded or paid based on flight profitability? I don't think saving $400 on sodas/snacks will really help whatever profit sharing program they run.

However here is one theory- let's say the plane is late for flight 123. If they are fully stocked for service on flight 123 then cancel service on flight 123, can they in theory turn the plane around faster at the next destination? I know the turnaround process with baggage, replenishment of service items, etc. is supposed to happen simultaneously but it doesn't always. So could some captains look for a reason to cancel service to try to "make up some time" during the next turnaround?
