Is carry-out food ever the correct order?

I rarely drive-up for carryout food. Its been a while and the other night i decided to “eat on the run”. Drove up to a White Castle restaurant and ordered their new “slider” hamburgers with tomatoes on it. Price was 79 cents each, ordered six and a large Coca Cola. After paying for my food and hitting the road, I discovered the tomatoes were missing! This was six miles down the interstate. I was not a happy camper. The missing tomatoes did not concern me as much and the principle involved. If they did this to me, they have done this to someone else? Question: Do you trust food orders given at drive-up windows? Have you ever been “cheated” out of food or given an incomplete order? If so, did you turn around and complain or did you just keep on driving?
