We live in an apartment building, where there are washer/dryer pairs on each floor. There are rules posted. The one about clothes left in machines says, "Please remove your clothes from the machines within half an hour after they're done. Clothes left longer may be removed to the counter."
I've only had to do this once. I folded the clothes loosely so they wouldn't wrinkle. There were some wild ladies' panties in there, so I made sure they were right on top of the pile. That'll learn 'em, I figured.
Another time, I knew whose clothes they were, so I went to their door and asked if they wanted me to move their clothes. They said, "Yes, if you'd like. We're tied up right now, but we'll come get them as soon as we can."
My recommendation: Give the clothes a short fluff to minimize wrinkles, then take them out of the dryer, fold them reasonably neatly, and leave them in a pile somewhere. If you have some grocery bags saved, you could leave two or three as a gentle hint to take all the clothes away.
