I work in a government funded university. I had to travel to London as an adviser to a day of government meetings. Fair enough the government ultimately pay me. I did however make the mistake of buying a coffee and a burger at the station on the way back! My entire expenses claim was denied (train/taxi/etc) because a lunch had been provided and the meeting was only one day and so only one meal could be claimed for. Eventually after much back and forth the govt dept sent someone to my university to 'explain things to me'. I can claim for one meal - but it didn't matter how much it cost! I could have claimed for a 12course banquet at the Ritz, but I couldn't claim for two separate slices of pizza - because that was two meals.
