Stockpiled Soap

I am officially stumped. Before I was only marganilly confused, but now I'm stumped. What I'm talking about is how some of the guys seem to either have a massive stockpile of soap stashed somewhere in there room or they can get it really inexpensively. Or it could just be that they're incredibly wasteful. I say this because it seems that just about every time that I go to take a shower there is a partial bar of soap in one of the shower stalls. If someone does have a massive stockpile of soap or can get it for dirt cheap they should let me know so that if and when I ever start running low I can go to them.

 

I'm sorry if this post is post included tmi for any of you, I just thought I'd share how stumped I am with you.
