Hahaha +1 for initiative mate that's very accommodating of you to 'allow' vendors to send you free coke, such a selfless gesture, we need more people like you on here willing to take one for the team. You could have an additional scoring method that increases the score depending on the size of the free sample, so say an 8 ball would guarantee an a+++ rating whereas 200mg only attracts a b- I don't buy into all the lab testing results anyway, my nose is the best lab there is and I don't need to send it to the N/L to tell me if it's any good or not.
