bad day!!!

I came thru Chicago Ohare awhile back and bought a coffee and some snacks at one of the airport shops, Then took a cab.
these were the only 2 Legit charges.
3 days later I went to use it again and the Account had been locked. There were random charges at a Target and other places 100 miles south of Chicago.
Unfortunatly we are at the mercy of the businesses, their employees and how they protect their records after we have left.
My fraud charges were reversed and I got a new card but it SUCKS!!
