My main interaction with USAnian coffee was in the Main Mothership of my erstwhile employer.
Every office and lab had the same 1970-issue filter coffee machine.
They were covered in the same fake wood sticky-back plastic that covered everything else: the cars, houses, domestic pets; rendering all beige. I think there must be a world-wide shortage of beige by now.
Now, there's nothing inherently wrong with filter coffee.
But these things...
The SOP was to open a pack of 'coffee', and brew it up first thing. The stuff was piss-weak. But it then sat on the hotplate for the whole day, slowly stewing into a brown gloop of horrendousness. To make matters worse, because one jug would not last the day, these infernal contraptions had a *second* hotplate on the top, so you could brew two jugs and keep them both stewing all day.
Oh, and beside the machine would be a dish fill of sachets of milk-substitute-white-powder, whatever that might be.
The jugs themselves had become irredeemably dark brown, the brown gloop having absorbed into the very glass itself.
<shudder>
My US-hotel breakfast experiences have been either the hotplate-of-horrendousness or the umpy-pumpy thermos things mentioned earlier. These are invariable empty, and the umpy-pumping just produces a brown flatulence. I can think of no place that these umpy-pumpy thermos things have a use, other than on a foldy-out table in the arse end of nowhere; audaxers, for the sustenance of.
