I'm clearly dining in the wrong establishments
I've eaten in some of the top-name restaurants in the UK and I'd struggle to hit $500 a head. They must've been playing in the deep end of the wine list.
Having said that: full marks to NTT for giving their Gods a kicking. In most companies, this would be found to be the fault of some lower-grade minion, who would therefore be caused to throw him/herself in front of the incoming flak and take the fall for Those Who Must Be Protected.
TBF it was probably the minion who was told to put the bill on their credit card in the first place.
