I might not be able to tolerate the type of coffee that happens to be available to me at some random gas station or cafe along the way. That hasn’t been a problem for me yet, but how about you?
Not really been an issue for me either. I’d say I notice more now when a coffee is slightly under/over extracted, but I’d probably have noticed it tasted 'weird" before and just not known what was wrong. That said, I’ve found it to be very rare. A lot of places just use quite forgiving dark roasts that are a LOT easier to make than more lightly roasted beans.
