its pretty tough........
" Hi, are you interested in any (your strain)?"- you
" Lets see some"- the dispensery
"heres a little sample, go ahead smoke it"- you
" Thats nice shit, how much you want for it?"-the dispensery
" umm how about $(what you would like for it)?"
"I think we can do that, because your shits so fucking dank my face is numb"-the dispensery
but seriously go to a club bring a sample and ask if they are interested. they won't think your crazy ,considering its a club and thats what they do
