I take great offense at you calling all shuls uppity if they use/serve brewed coffee.
Lots of us are old enough to remember when instant coffee was much more expensive than brewed coffee. Shuls could easily brew 40 cups from a 99 cent one pound can of Maxwell House…and accumulate free haggados.
I’ve never belonged to a shul that served instant coffee on any kind of a regular basis. That said, they do keep a jar of instant decaf in our shul…I’ve never seen it used and think it must belong to the sisterhood, not the shul itself.
