Visiting/Visitors

What do you do when you visit somebody's house and you find out that your reputation as a "coffee expert" has preceded you? Everybody was hesitant to serve me coffee at the few places we visited over the holidays. I tell them if I ask for it, I can't complain, and I won't. Have I been disappointed yet? No! Everyone seems to be using smaller roastery beans (well, for Calgary), and I don't think anyone had preground. The only thing I am finding is that most cups aren't complex. But that makes sense, none of the coffee used is very fresh, nor ground properly, but I haven't had a bad cup (all drunk black). Even so, I try to add a few comments of places for improvement while praising what they're doing right.
