In my company (greater than 10000 employees) the travel team works for procurement.

Some of the gems that they have come up with.

Frontier is a acceptable airline if the fare is less (to be fair, after much complaining this was changed)

Avis is the only way to rent a car.

You must turn in your entire meal receipt including what was ordered. They actually have a written policy somewhere that says alcohol cannot be more than X% of the meal when with customers.

They also have the you must use the corporate credit card policy for all purchases (since they get a kickback). Which got me to wondering, since I have to get the credit card, the bill comes to my house, how is this a benefit?
