Actually, Gimpy Jim has it right. Despite popular beleif, Zappa was very much against any and all drugs.

The Cosmik Debris are the drugs, cosmik like psychedelic far out etc.

"He said, for a nominal service charge, I could reach nervonna t'nite"

For a little money, he could purchase some drugs and get so high he'd fee like he was in nirvana from the drug enduced pleasure.

The shaving kit was more than likely heroin, as that's how most people carried that stuff (see the movie "Ray" for example)

It's basically Zappa saying that all the dealers that saw him as such a far out musician thought he was some kind of druggie and thought they could make some money selling him drugs should look to do business elsewhere, because he's above such things.
