(nesting limit)

If I go into a store I am not pulling out a marker and putting big Xs on products I don't like.

The supply of those store is already miss products whom demands are already nullified by 'big shareholders'.

For e.g., I cannot go to a store and buy heroin, though, I'm pretty sure there is a demand for it. However, I would like to mark it as bad if I were walking next to it in a store. That isn't nullifying the demand. Who want to buy it, will buy it.
