If there was a
serious level of personal expense involved, I could accept the claim. For £7 or so, it's a joke. However, if his staff/secretary does it for him, and it's buried in a skip load of other claims, I can excuse it falling though the net of his conscience.
That said, I worked with (
not for) an RE lt col who would assiduously claim his £0.52 bus fare when he visited other MoD buildings. But then he would also only drink coffee in the morning and tea in the afternoon. The RAF guys in the office told him to get on with his personal preferences, and just brewed for each other.
