Slightly Spilled Someone's Meal; Still Got Tipped & Upvoted

The food was inside a styrofoam package placed inside a plastic bag, but as I had to put it in my delivery backpack vertically so it could fit, seemed to have caused some of the sauce inside to spill to the bottom. And obviously as I'm delivering by bike, any bumps on the road and sidewalk will make it even worse, although it is the fault of the restaurant for not fully securing the container, since if I do it myself that's considered tampering.
