A while back before I was issued a mag-key to get in to my office, I left on a Friday evening planning to get on a plane the next morning for a trip and I left my phone on my desk.
I had to borrow a friend's phone, call around to the few managers I knew who had keys, and ask if I could borrow theirs. I then proceeded to make a round trip of about 30 miles from my house, to the other guy's house, to the office, and back home.
BUT....I wasn't going on that trip without my phone.
