Frustration

Something is wrong in a society where a person who works in a music department of a quality store is clueless about classical music.   Since I live in the country, I called a local store wanting to know if they have Mahler's Songs of a Wayfarer, thus avoiding a wasteful trip into town. Calling the store became an exercise in futility.  Here is the conversation:

Me:  Hello, I'm calling to see if you have Mahler's Songs of a Wayfarer.
Store:  So what group is this Mahler fellow in?
Me: He is a composer and not part of a group.
Store:  Oh.  Well then, does he spell his name M A L E E R
Me: No, that would be Maleer.
Store: But isn't that what you said when you said Mahler
Me. No, it's spelled M A H L E R
Store: Oh, Ma  as in Ma and Pa! Cute, but why put an h in it?
Me: Do you have it?
Store:  I'll check. 
Five minutes pass, and I should have been worried when the background music was a rap tune.
Store:  What group would he be in?
Me: I told you he's not part of a group he was a composer.
Store:  Well, I mean did he compose jazz, or rock or rap?
Me: Oh, you meant genre?  Classical.
Store:  OK, Ma'am classical what?
I know,  I should have given up, but I pressed on, "You know, classical music like Beethoven.
Store:  So what group is that guy with, and maybe I can help.
Me: Never mind, I'll drive in and look.
