Re: Too many stories like that one.
Challenging expenses. My last employer tried that exactly once on me...
Claim comes back with a snotty note: "REJECTED - RECEIPTS DO NOT MATCH CLAIM"
So, I drop the head of Finance a quick e-mail:
"Dear Sir
With regard to your recent note, I would like to point out that on the day of the claim I spent seven hours travelling, followed by seven hours on-site recovering the central file and print server after it crashed. If you're going to quibble over the price of a sandwich and a cup of coffee from a greasy spoon cafe, then I can either (a) Eat at more expensive restaurants just so I can get a receipt, or (b) I'll just send apologies for absence to every off-site meeting and make us look like the insular mob we truly are. Please advise me how you wish me to act on future events".
I didn't get an apology or an explanation, but my claim was paid in full and all subsequent claims went without a hitch.
He who lives by the snotty memo, dies by the snotty memo.
