No kidding???

Gee, wonder who I talked to this morning, they sure sounded like they 
were the manufacturer...  Let's see -- yeah - talked to Mimmie Kahill at 
732-982-8535 - Answers the phone American Oil and Supply, Co.

Oh, well that cinches it. After all - a government who pays $640 for a 
toilet seat surely wouldn't pay too much for anything else. So obviously 
I'd be foolish for even asking.

Well when the guy at American gets back from his trip and calls me next 
week - I'll tell him I've just learned that plain ol' 10wt motor oil is 
just as good as KS7470, and he ought to be ashamed of himself selling 
KS7470 for so much! (Maybe I should wait until he tells me what the 
price is BEFORE I rip him up? - Naw! - more fun to shoot from the hip).

No I'll just apologize for wasting his time, and thank him for returning 
my call.

Should I do that BEFORE or AFTER I ask about an "off-the-shelf" product 
that meets the specs (Since we now know we can't afford "the real thing")?

> Keep those machines running and well oiled.

Actually - that's what *I* was trying to do, before I realized how much 
time I'm wasting.

Sheeeesh.
