So why'd you ask?

Here's one I never understand.

Scene:  Two guys, one browsing the vinyl (he has an Enya album picked out), the other clutching a binder to his chest, dreamily looking at the ceiling.  I'm playing the most recent Esmerine album which is mostly instrumental and currently on a fairly quiet track featuring guitar and marimba.

Binder Clutchy Guy (to me):  What is the name of this music playing overhead?
Me:  It's a group from Montreal called Esmerine.
BCG:  Oh?  It's nice.

BCG (to Enya Vinyl Dude):  This is nice, isn't it?
EVD:  Hm, what?
BCG:  What's playing.  It's a group from Montreal called Esmerine.
EVD:  Ah?  Yeah, it's nice.

A few more tracks play while EVD browses further and BCG looks at the ceiling.

BCG (to me):  Do you sell this particular music here?
Me (reaching into display case and handing it to him):  Sure, it's this one.

BCG looks at it (it's sealed and $16.98) front and back, probably seven or eight times.

BCG (to me):  Is what you're playing a selection of tracks?
Me:  No, it's that album you're holding.
BCG:  Oh?  It is?
Me:  Yes.

BCG flips the album back and forth another three or four times, puts it back on the counter.

BCG:  Thanks.
Me:  No problem.


A few more minutes go by, EVD buys his Enya Vinyl and they both leave.
