Like Rainwater from an Ashtray.

There's nothing quite like the flavor of coffee, that makes your mouth taste like you just drank rainwater from an ashtray.  That's what the coffee from that last gas station did for me.  It was too early and too long of a ride ahead, with that robustly repellent flavor sticking to the inside of my mouth.  As I rode on, I imagined that they had put a partially smoked cigarette butt in the coffee canister, because "it's their secret recipe" or something like that.  But like many nasty things which have come before it, I somehow managed to ride on.
