That's right! You don't see my green until I inspect your green. Would you stand outside a grocery store and hand a stranger money to go inside and buy you something to eat? What if it's something you don't like? How do you know he will return? He could come back and say "i lost the money, it must have fallen out of my pocket."
More than likely, the "dealer" needed 85 addition dollars to reup. So 85 + what money he already had.
I have gotten more than $85.00 for a blow job. Did I say that out loud? LOL! Just joking, I think you have figured this one out. Lesson learned? Cash exchanges for product and do not trust anyone. It keeps you out of jail or drafting someone who cannot stay off the radar. Probably had his baggy pants on in FL.
