I don't distinguish so finely. Even with out overtly saying something allowing someone to believe something is a form of lying to me.
I use "dishonest" as the broader category and reserve "lying" for intentional falsehoods. I consider lying a form of dishonesty and "allowing someone to believe something" as another form of dishonesty but not actually lying.
However, I do not apply that in this case. Even if you were fleecing the marks on the street. It is not dishonest at all.
I think its dishonest because you're tricking people (and tricking them out of money would just make it worse). I guess if you worded it (what you're telling them you're going to do) right, then there would be no dishonesty.

! relative morality
The absolute would be that all forms of unecessary dishonesty are morally wrong.
The relativity comes into play in deciding if and when it is necessary to be dishonest, and which things are, in fact, dishonest.
it is easy to tell I'm a godless atheist isn't it?
