Use it anyway

You decided that you will take the chance and use the shower anyway. It is still pretty early and hopefully you will be done before anyone come back.

You place your bag on the near by bench and walked over to the showerhead.
You turned the water on and to your surprise,the water came out clean and clear.

Happy with the water condition,you undid your bikini top and bottom and place it into your bag before heading back to the showerhead. You step into the water and begin to wash your body.

When you felt you gotten clean of saltwater and sands,you turn off the water.
As you turn around you noticed your bag was gone from the bench where you left it,looking over at the door you see the back of a little homeless girl running out and in her hand was your gym bag.

You just got rob bitch....

The bag was your only bag you brought along for the trip. It had all your things in it.(ex:clothes,wallet,phone)

You're now wet and naked in a homeless camp.....
