I've been staying in a hotel in Charleston, SC for the last week. Every morning I open a packet of soap to have a shower, leaving it on the provided soap dish when I'm done - I've used 10% of it at most. Every evening, the 90%-of-a-bar has gone, and a new, wrapped one has appeared in its place.

I can understand that some might like the luxury of fresh soap everyday, but I want to know is what happens to all the 90%-of-a-bars of soap every day? Are they returned to the factory for recycling? Smoothed off, rewrapped, and sent to cheaper hotels? Is there, maybe, a vast landfill somewhere containing nothing but 90%-of-a-bars of soap??
