Oh you only want to talk about Missouri law?

For the sake of clarity of context I'm riposting my argument for the casual reader:
Dependent Variable (the point we're debating):
- Private person > Private Business.
Independent Variables (the scope and context under which the point being debated should be true):
- A right specifically enumerated in the Constitution.
- A right which is otherwise being lawfully exorsized.
- A private 'real', 'natural' person exorsizing the right.
- A private business forbidding the exorsize of that right.

Now lets have a look at your link:
Items 1, 2, 3, 4, 5, 6, 8, 9, 10 and 17 do not qualify under Independent Veritable #4 as I'm
not talking about police stations, air-ports, federal buildings or schools.
Item 7 doesn't qualify under Independent Variable #2 so long as the person carrying the firearm is not
consuming alcohol. This is why many states now allow guns in malt-beverage-serving establishments. Therefore #7 should be repealed.
Item 11 is without evidence that the mere presence of a concealed firearm is any danger to children. Without the ability to meet strict scrutiny this law is unconstitutional and should be repealed.
Item 12 is justified due to the high consumption of alcohol by all patrons and the emotionally charged nature of gambling.
Items 13, 14, and 15 are without merit since the mere presence of a concealed firearm is not a danger to anyone.

So from your link, riverboat gambling is the only private business which has a 'need' and is thus justified in banning firearms. I would add to that any business which has above-ground refueling tanks or other hazardous chemicals.
