when i started getting cut shit/overpriced shit from one source, i started to do things to him, like - give him good drugs in exchange, but not enough to equal the amount i owed him in cash... then later give him the rest of the dough he said i owed him -- which turned out to be totally fair, imo. i think i surprised him giving him the money and not cheating him or making excuses like some of his other clients
after that, we became better business partners, almost friends really..started hanging out as friends, and tossing each other freebees now and then
trust and respect are important. if you can earn them with someone, it's a very beautiful thing
when i was younger, i'd deal with anyone who i knew had what i wanted. now i only deal with people close to me that i can trust and respect. it makes life much easier and more enjoyable
