I have a corporate Amex card, and even though its a "Corporate" card, given to me by my employer, it is in my name and I am legally responsible for it. My company will reimburse me for my expenses if approved by my manager. I have always thought this was a liability and weird, but everybody else at the company (a 500 company) thinks it's normal. So any expenses not approved at the end of the month are my responsibility. Anybody else have similar experiences?
