It happen to me, I call myself checking to make sure my pump was not tampered with. I got lucky though, I happen to call my CC company to find out someone was trying to buy stuff at a department store for over 200. But was decline by the grace of God. I kid you not, my shop was around 5 that afternoon and the CCard was being used within the hour 45-50 miles away. Needless to say I have not done anymore shops that required me to buy anything. Not worth it for me
