It's scary, I must be meeting the wrong people.  I know some store
managers around here that run Radio Shack's - and one at least who just
works there, no longer manages, to prevent migraines.  They're actually
honest enough to know what they don't know & admit to it;  Of course,
these are the managers, not average sales floor folks.  Those are
usually better at catching shoplifters than telling me where store stock
is <G>

I've found one thing - getting to know who at a given store is who, does
help - if it just helps them know you & know, that you know what you're
talking about.

Having had a family member use my microclip leads (The ones you snap
onto DIL leads to watch Vcc for stability, right?), to check amperage
out of a 60A car alternator once (they borrowed my DVM without my
knowledge!) - I'll say this:

LOCK UP YOUR DVM & OTHER TEST GEAR & TEST LEADS!  <G>

There are people for whom "common sense" doesn't mean the same thing as
it does to all of us.  Could be that the RS employee Wagner was talking
to was worried about someone setting their house on fire, same as my DVM
almost got set on fire there (The microclips saved the meter, by glowing
red & becoming straight little pieces of phosphor bronze, instead of
hooked.  10A fuse didn't even blow.  Person's sold wire in the past, but
wasn't THINKING, I guess!)

Could be that that RS employee needs to get to know Wagner & get a clue,
that Wagner knows what he's talking about! <G>

Could be that the RS employee needs to learn, not just fake it,
definitely <G>

The other possibility is that the RS employee could've been having a
really bad day, with headache or something.  Sometimes connecting on a
personal level lets people get along better & not defend themselves, I
know doing that makes life more fun for me.
