Didnt you help found the club or something?
That is a good point about bringing stuff from home though. Still in this hobby I am yet to see anyone steal anything, on purpose. Books, dice and tapemeasures go missing. If someone was the type to steal a drink, wouldnt it be more worthwhile to tip a dreadnought into a pocket?
I think the fear of people finding out is quite a deterrant, I can think of at least two people at club (Psycho and myself) who would respond to a thief in much the same way as a pit bull, while the sheer disaproval and blacklisting from the rest of the club, and worse, informing of parents would put the fear of god into someone.
Besides this game is built on trust. Trust that your opponent wont cheat, that he/she will treat your models with respect, and wont go around pilfering.
Normally I'm the last one to expect anything from people but deceit but our club just doesnt seem full of sticky fingers.
