The 10 quid you spent at least got you high right? Shake is not the best but works for me if that is what I can get. If it wasn't good, as you said just don't go back. I used to get so mad when I would buy hash and it had plastic in it. A friend with a smart shop in Amsterdam said the guys used to stand around and laugh as they sent the hash to England. I would feel so disgusted if I found plastic in the gear. At least I could see it to pick it out...dread to think what was in it I COULDN"T see! yuck!
