It still matters what is the standard, even if you can find alternatives. It admittedly may matter more to a traveler who goes through airports and middle class hotels though, than to people living there.
For sure. I just hear the "I went to the US and there was no REAL bread to be found" and I'm always a little confused. Even the local grocer in my fairly poor neighborhood growing up had a section of bread loaves in various styles. I'm sure the selection is worse if you're in a more rural part of the US, but that's probably also towns that maybe never had an actual baker even when they were founded, assuming they were founded in an era that would have been reasonable.
