I was buying gas at 2AM in Grand Forks, ND on my way back to my parents home. I had stopped at that same station multiple times, but Citibank denied the authorization (plenty of money, and I only used that card for gas). I foolishly was about $5 short on cash[1], had to call Citibank and yell. Had to walk to the across the street that had an ATM that would work with my bank card (gas station ATM didn't have the network). It was a typical ND winter night. The failure mode on getting permission is really nasty. Thinking about it, they really had some sh!+ software at that point since I only used the card at 4 gas stations with 1 in the Plymouth, MN and the other three on the I94 / I29 route. 1) after this I started following my Dad's policy of hiding $100 in the car for emergencies.
