if you left the chammy on the ground, wouldnt it be wise not to use it again? From what i heard, the dirt particles can get caught in it - and when you use it next time it can scratch or something. dont know how true that is, but I get a new shammy if mine fell to the ground (happened twice already). So, if that chic did take your shammy - then shes gonna be suprised when she sees her car is full of scratches
