Also forgot my all time favorite,

Because of our world class expense reporting system, any international trip can only have one exchange rate per currency. So if you travel all over the place and have to change currencies, that can really hurt.

So they came up with a workaround. (the procurement people did).

to balance currecncy flucuations just add a cab ride or two to your expense report to ensure that you are getting a full re-imbursment.
