Have had much fun with these pieces of soft dogshit.
String 'em along.
I've strung them along for months as I recall years ago.
If they need you to send 10k, inform them you have access to 8k. After they cave to 8k, tell them it was sent and give them a tracking #, etc, etc, etc, etc, and etc.
If your end will be 22 mil, tell them after further intense review your end should be 26 mil in all fairness.
Be polite and professional.
Drop the bomb and unload on them whenever you think their infected pussies are good and wet.
