In the spirit of good coffee posts so far...
I was assigned to my duty station after boot camp, at the ripe old age of 17 and had not yet taken up the habit of drinking coffee. As the junior man in the division, it was my assigned job to have the coffee made before 7am when everyone came to work. Every day I took the pot to the sink across the hall, and made it the same way every day, for at least a month. Now, remembering that this was my first trip on a Navy ship, one day I just used the same sink, but filled the coffee pot from the "other" faucet on the same deep sink. Everything went fine, and my 2nd class came in and poured a cup of coffee. He drank it black and tended to let it cool a little before taking a big swig. This particular morning went about the same, and he started working on pay records laid out on the desk in front of him. Then he took a big swig and sprayed a large mouthful all over the desk, pay records and even on the wall behind the desk! He called me over, told me to get a cup and pour some into it. I told him I didn't drink coffee, but he insisted. When i took a sip of the coffee, I immediately tasted a slight hint of coffee covered up by a strong salty taste. He wanted to know where I got the water for the coffee pot this morning. I told him the same sink but the other faucet. He told me that the "other" faucet was to rinse mops and was seawater straight out of the ocean! They continued having me make coffee, but he started taking a sip instead of a gulp when pouring a fresh cup.
