If your boss gave you a credit card . .

[Alex Alex Dawson oo! oo!]

I had a corporate Amex Card when I worked at GSK; wouldn't dream of trying to use it for personal purchases.
The company now has a system of self-certifying expenses because of the management time being wasted in checking these every month - however, Corporate Audit undertake random checks so if you're found out it's gross misconduct and instant dismissal with a reference that will probably include this.

I've got one and believe me every penny I spend on it has to be accounted for.

This!

Unlike my broker/trader friend who spends literally whatever the hell he wants on his.

Brian Clough used to buy his chums lunch and then hand over the receipts to the recipients of his generosity, so that they could claim the price of the lunch as their own expenses. That way, everyone could be on the fiddle.

I use a separate credit card for all works expenses so have two credit cards.

Works out much easier so that what is owed is paid off so to speak.
