Just the really clumsy straight out way he just approached and didn't even ask for anything particular with "Is there anyway we can get what you are having?" also looked dead sober and any regular person would at least try to strike up a bit of a conversation in a pub/bar first especially in a place like Kalgoorlie. I just replied I don't know what you are talking about.. A friend and myself had taken a couple of Es earlier and I usually looked affected by them pretty easily.How'd you know he was undercover?
Should have just messed with him and said something like sure just meet us latter at 2am in some dodgy alleyway in Boulder.
