Multimillionaire sensitive about travelling around on rock-star bus

Multi-Multi-Millionairre Treasury Secretary and former Rail Transport CEO, John Snow, mentioned twice to a reporter that he thought it was unfair she used the phrase "luxury bus" to describe the Transport for the Three Secretaries, Chao, Evans and Snow TOUR. Thanks to comments which C-SPAN cameras caught, Sec Snow complained to one reporter that used the phrase "luxury bus." Another reporter stuck up for the Three Secs and said that the American people would not be concerned. Then Sec Snow repeated his complaint (almost word for word). On the one hand, there is no doubt in my mind that they could have, in the realm of the possible, each had their own bus, which would be significantly more costly. On the other hand, the reporters are getting by on a Charter Bus that looks like any Greyhound, while the other Bus was, according to its driver, used for Rock Stars. So, calling it Luxury Bus is an Understatement.
