The trick is, my friend, you don't. You just zip it up and don't ask for more. If you are offered a second cup you just tell how lovely their kicthen(/dining room/library/what ever the place where you are having their coffee) is.
Is there is no gentle way to say, tell them that you don't drink coffee from the pig's pen and you'll go help them get the right kind.
ask for tea instead. You can't screw up tea much.
any coffee's good coffee
I have ran into this issue but it was with a dish a gyg i worked with made...it was a "Salmon Ball" (creme cheese and raw salmon)...he ranted and raved about how great it was.....i took one bite and he was like isnt it great.....and i bluntly said "it tastes like ****" and through it in the trash.....later the majority of the co workers thanked mefor speaking up.....and needless to say...he never made it again<br />
i guess i am just a blunt person
"Hey, your coffee tastes like ****."
THIS EFFING COFFEE SUCKS! lol Say 'What brand of coffee do you use? (Say you use a different brand) Then say 'It must be my tastebuds because I'm used to a different kind of coffee and tell them that you don't like it.'
Just don't drink it again.
Take a sip and hold in that awful face I really want to make gulp it down and smile...you that was just so good..hahah :)
What is this steaming hot swill you have given me? Then offer to teach them how to make coffee.
