Stone shouldn't be able to buy/sell guns, the Doctor shouldn't buy a lot of things.

Also: the repair button must be exclusive of weapons shops 
i dont think that edwald is a good choice to repair the exterminator and Duncan is more like "destroy object" than repair.

I've been giving this a bit of thought, and I think an implementation of this
would have the additional features:

1) some sort of lua file that lists items which would be 'classes' of forbidden
items (e.g. guns) -- so we we could reuse them with various npcs
2) some sort of visual indication that the item cannot be sold (graying it out?
maybe a red x in the corner?) and some sort of tool-tip text explaining why
