I loathe Wal-Mart. Disregarding
the economic damage they do to local businesses and the negative effect they have on manufacturing in the US......
They sell cheap crap and their customer service is horrid.
Treebound has a great point. That's one issue that might be worth a threatening letter from an attorney. Sexism isn't correct, regardless of the gender of the victim. I'm not saying "SUE 'EM", but a letter from an attorney letting them know that they are opening themselves up for a possible lawsuit from someone less reasonable than you might not be a bad idea.
And I never did understand the "safety" argument when banning bicycles. Have they actually seen how their customers drive their cars and pilot the shopping carts? I'd think that one guy wheeling his bike in to secure it to something solid would be the least of their safety worries.
Seriously - if at all possible, I avoid Wal-Mart like the plague.
