Experimentally, didn't Wal-Mart, in another city, actually split its store in half, subdividing merchandise with two managers instead of one?
Though they didn't do this, the logical thing for them to do would be to split their store between Wal-Mart and Sam's Club. Any further efforts to oppress them through legislation would then be combatable with paperwork-only changes.
But the bottom line is that Wal-Mart has a healthy attitude towards not dealing with extortion, be it the frivolous slip-and-fall lawsuits they get a handful of a day, or some legislative body trying to rip them off.
Hopefully, what they come up with will leave those aldermen squealing like piggies.
I testified for Wal Mart a few years ago as a witness to an obviously set up slip and fall.
