Admittedly I did not read the original article, nor this thread.
I will say this though. Catering for private aircraft is stupidly expensive and over-priced and is pretty much controlled by the "Fixed base Operator", the gas station and terminal for private aircraft. They ahve a captive private jet flying clientele and they pay whatever the price is. Hence the grossly inflated pricing. And usually sub=standard food. A fucking vegetable crudite plate for 6 costs like $150! I have no idea what long haul meal prepped menu's like those described costs but I'd be surprised if dinner costs any less than $200pp.
Having said that also, the optics are bad and if Trudeau had better political acumen he'd pay someone $200k to find a way to self-cater these meals so they do not becomae such a (justifiably) outrageous scandal-worthy pissing away of taxpayers money.
Think about this. $220,000 is the amount of federal income tax that it would take TEN TERB members making $120k per year to pay. Just to feed and water these hogs for a routine trip.
