The situation is accurately described, there is no spurious claims involved or intent to defraud. An event took place at 8pm which the person was obliged to attend. They had left work as normal at 5pm. Their home is 10 miles away from the office and the question are they entitled to claim for the journey to and from that event (20 miles). It seems unfair that they cannot claim for the actual additional mileage they incurred particularly as night-time events are painful at the best of times, without feeling that they are out of pocket as well.
