should ewf sell out to the man?

So I get this email from polimedia.us (despite their domain name being registered in Miami, their website seems oddly, er, Romanian). And it says:

We have reviewed your blog on behalf of one of our clients that would be interested in placing advertising with you.

Oooohhhhh, noice. Apparently they are acting on behalf of doingfine.org (tagline: "We're Doing Just Fine").

We'd like either a 150x150 button, 160x600 skyscraper or 468x60 full banner (or footer). Alternatively, we may be interested in text-only advertising.

Uh huh, uh huh. SHOW ME THE MONEY!!!

This would be a weekly, monthly or yearly arrangement. In either case we will require a one time, one day (24 hours) free placement in order to test the quality and quantity of traffic your website can actually provide.

So no money straight away? And I have to give you free advertising?

We prefer using PayPal but may be able to accommodate alternative payment methods.

We have a deal breaker! I send this response:

I would like the money in a brown paper envelope* rather than paypal.

They counter-offer:

That'd be a little hard to do.

Sorry guys, no free advertising for you. Oh, hang on...

*It's a tax thing.
