Just naive.  Most people make assumptions about what was promised.  If it
sounds too good to be true, it probably is.  What the sales person 
promises, the fine print takes away.

You will find out no one will sell to you if the contract requires some 
things, and the alternatives are rather limited.

I would be more concerned about suppliers that promise things that aren't 
possible than suppliers that decline to sell things that aren't possible.
Unrealastic buyers are just as much of a problem as non-performance by 

If anyone promises their network will never do down, they will never have
single paths, they are perfect; you should grab your wallet and run away.
