Then wastage is vast!
The stories DH comes home with would make me laugh were it not for the fact that it's all tax payers money!
For example, civil servants (thinking that because they with the forces, they are in the forces and have the rank they are paid the equivalent to!) they should take every opportunity to go from Bristol to London first class. why on earth, they can't take economy, like DH, I don't know.
DH asked them and they replied, it was their right to travel first class so they would.
Meetings that didn't actually happen or when DH got there (having paid around £200 of tax payers money for the train), the guy in London gave him 5 mins of his time and then said he was off somewhere else.
Some of them don't think about the wastage at all.
