lol you sound like your Avatar kinda, like some grumpy old man, i LOVE it ))) (i now imagine a grumpy Bill Murray picking Legos one by one at a PAB wall lol)
I shall do the same at that PAB wall though, fuck the kids!
How much do you pay for such a cup tho?
I have taken a couple of minifigs from a kid, after he picked them up from the shelf I was placing them on (I was finding the ones I needed, and getting them out of the way).
My local store, large cup is $14 and a small is $7 (USD).
