What Items Are Ok To Steal From Hotel Rooms?

Ok, "Steal", might be a little harsh, but you know, the little items that seem free for the taking at hotel rooms! We always takes the extra toilet paper, pens, stationary, soap & lotion. This time around, I also snagged a shower cap, and a mending kit, because you never know when I might need to sew!

I feel like this stuff comes with the price of the room, like a guest tax LOL! I was tempted to take a washcloth from The Peabody in Memphis, because it had cute ducks on it. But, that actually seemed like stealing, and I was afraid they might keep track of them. I also have a large collection of room keys, I'm not even sure why. Do you take anything from hotel rooms, too?
