I suppose you could come up with the same result and probably better if you asked this question to yourself instead. I.e. by making a purposeful list in advance instead of just randomly selecting stuff while in the store.
Another factor is that having the menus come from an outside source keeps them 'honest', I wouldn't 100% trust myself not to include some of the crap I was precisely trying to get rid of If I made them from scratch
The result was surprisingly good... maybe not 100% right, more like 90%, but good enough to overcome that friction.
