OT - In response to RKF ^^^^^, I once worked for a company where travel was four days a week, overnight stays, and many flights a month. Once hired, I was told to use my charge cards and expense it out at the end of the month, with reimbursement by the 10th of the next month.
After getting my breath back from such an unusual request, I told them my charge cards were for emergency use, not company business. We had a few exchanges, one being the threat of losing the job. At that point they could have their lousy job! Eventually they gave me a company credit card - which had been the norm at other companies in this type of position. Found out later through peers, this was the way the company treated new hires. Most people on the road used their own credit cards after being presented the same scenario on the first day. It is amazing what people or companies will try to get by with! All for the almighty dollar!
