What would you do?

I've had reconstructed logs accepted in audit.

But you do need to keep a log even if you take actual expenses; otherwise how do you determine what the actual percentage of expenses to take?

I'd take the miles with a reconstructed log, and hand him one of the mileage logs I keep in my desk drawer for all new biz clients. Sometimes I have to beat them over the head with it.

I agree and I would add to the I would include the expense if the client understands the possible consequences and still wants to claim it. It is not my decision it is his.
