Flew in there yesterday with a fellow UND aviation alum. Wanted to go over to UND and see a few friends that still instruct there. Went into Flight Support and when they found out we were not going to purchase fuel the girl seemed annoyed. Then when we asked for a ride over to UND flight ops she rolled her eyes at us! When we came back to leave we had to pay 15 dollars for a "facilities" charge. What a joke!
