I worked there and I have seen people fired for unauthorized charges - non-Nike = on their credit cards.
One idiot lost her job because she used her Nike c/c to pay a utility bill. Some others were let go because of a gift card problem which I never totally understood but they were a good hardworking team and they were gone.
My ex-wife was the executive assistant to the VP for PACCAR (Peterbuilt & Kenworth) the top executives were forbidden to own any from vehicle manufactured by a parent company of a competitor.
So this kid might have been using her corporate card.
