Or are otherwise able to claim any expenses at work?

I technically did at my old place, but no one ever bothered since the system was such a pain and unless you were using your own car and needed petrol money, it wasn't really worth it.

At my current place, people are all over it, I'm waiting on a company credit card and people get everything they can. I don't know the protocol though, Like when I went away the other week for week, I bought a coffee at the airport - is that an expense? I would have bought a coffee anyway.

And where on the form do I put 'hookers and coke'? Under miscellaneous?
