That has to be the most assured way to get shot that I could imagine (though it would be funnier than hell if you actually pulled it off).
For God's sake, get a pistol. There's no need to be a martyr for what amounts to worthless property that I assume is not even yours. From a capitalist perspective too, you die trying to defend a few hundred or thousand dollars and the business will lose that in higher insurance costs, the lost sales that will result, etc.
For example, if you get stabbed trying to defend a beer run out... is that really economically sensible from the business owner's perspective? They probably would rather have lost the beer (and obviously your life and human life are worth far more than material goods). Or if the person runs into traffic, gets hit, dies, or lives, and he or his family sues the establishment alleging overzealous and/or unfounded reasoning for chasing him into traffic. At the very least court costs will mount up (even if the establishment wins) and you'll be terminated for whatever reason is available.
What I'm thinking reading this is that it should be an advertisement for GOA. Anti-gunners have gone so far that people contemplate throwing hot coffee in someone's face to defend themselves against violence. If that doesn't make people reexamine this ridiculousness I don't know what would.
1. boiling water to the face is the end of any persons ability to shoot.
2. It's not about property, its about disrespect. Anyway, I work with "metals" and "3d modeling"
3. Holding a cup of boiling water in your hand will not even register as a weapon to an armed robber.
4. firing off a weapon in a public area has a chance of hitting innocent bystanders, and often will stop somebody from firing.
