I'd ask if he is going to pay for a new suit and shoes!
Don't go there Len. I've just had to pay for £300 of flights and £600 of hotel out of my savings because they "Don't do company credit cards" and I have to claim it back on expenses. Pretty sure asking for money for shoes and a suit will go down like a sack of sh!t.

I wouldn't be going to work if my company expected me to do that. If they need me somewhere, they can pay for the flights and accommodation to allow me to work there by what ever means possible.
Essentially what they are getting from you is 0% finance as I assume they would pay it back at the end of the month.
