I usually take home whatever is left when I leave. The shampoos I hang on to in case a hotel forgets to replenish or when we stay at a relative's house. The lotions and conditioners I seldom use, so I collect those and unused shampoo and we donate them to the local Ronald McDonald House. I wouldn't make a habit out of snagging full bottles every day (even for a good cause), but the folks at RMH are glad to get the donations. We usually throw in a few travel-size shampoo bottles that we buy at Target just so they aren't stuck with too much conditioner and lotion.
