the Fremen were "modeled" on (Frank's conception of) the Bedu (Bedouin) of the central Arabian Peninsula;
as stated above, coffee (and stupidly strong tea) is the center of social ritual (Bedu coffee is bad-ass strong, too ...
served in an itty-bitty cup, about three or four times stronger than espresso)(and off the top of my swollen, bloated
head, I can't call the name of the type of coffee beans used, but the result is a disturbingly dark green, thick liquid,
like 50:1 oil-gas mixes for chainsaws ...)
being a traditionally "nomadic" culture, the Bedu kept their personal possession light, for travel, and the coffee service
was (and is) a prized possession (often passed down for generations - even in a "modern" Arab's home, you must
hear the complete story of the life of the coffee service from your host before taking the first sip)
altho not specifically stated by Frank, I'd assume that a Fremen's coffee service would be among the handful of
"possessions" considered important, and one of the few things packed-up and taken with them when the tribe
was "on the move" ....
