Those Damn Doobie Dogs... Need Help.

I have not bought any weed for myself since the middle of summer, and have a deal arranged for tommorow. The guy is getting me my 1/8th at the beginning of school. Everything seems fine and dandy, but drug dogs were on campus two days ago and my life would basically be ruined if I got busted. I'm wondering if anybody has any ideas that could help make for a safe exchange.

Also, this guy has never sold to me before and he says he doesn't have a scale. I told him a funny story about someone who tried to sell me a dime bag before for 50 bucks and that I'm not stupid, which was my indirect way of telling him not to rip me off. I hope I didn't offend him- but he's a really chill guy so i doubt it. If he shows up with an extremely undersized 1/8th however, I am not sure what to do.

Anyways, any advice on either of my issues would be greatly appreciated.

By the way, I don't have a car.

Meet him off campus.

i am getting the weed first thing tommorow and i dont know how to hide it from the dogs if they are at school by some weird chance..
