I had a 3work trip to New York. Originally it was 2 arseholes colleagues and not me, but our boss added me on, enraging the 2 arseholes colleagues.
They froze me out of all discussions, wouldn't tell me their travel plans (I only knew from the nice lady who booked such things, who kindly told me) and I ended up on different flights and in a different hotel. Arseholes.
They skived off most of the work and left it all to me, and on the last day (only time I saw them) I said to them at lunchtime that I expected they would be leaving soon to make sure they caught their (rather early) flight home.
Arsehole no1 said "Oh ffs, Fromage, I think we can manage to make our way back to JFK fgs!"
I smiled and said "Of course you can" and walked away with my dignity, as Arsehole 1 continued to bitch about me loudly to Arsehole 2, who did seem a bit embarrassed about it all.
Later I saw them in JFK, apparently having indeed missed their flight and desperately trying to get on something standby. Good.
I was not surprised at this at all.
Partly because I knew they'd not left enough time to get back to their hotel, and then to the airport.
But mostly because I knew their return flight was from Newark.
