I'm not sure what type of lawsuit you think you'd be able to file, and I'm pretty sure the tens of thousands of dollars it would cost you out-of-pocket to do so would be worth a discount on 20 bags of mulch.
I'm glad that the District Manager is being helpful. Hopefully he will get you the resolution you seek.
I am hoping he can too. But any one that spouse has severed in the arm forces and did not take that spouse's last name. This would include spouses that choose not to take their partners last name, like professional woman that chose to keep their own last name because of their career. and which to hold on to their independence. This would also hold true for same sex marriages where neither one of the partners take the others last name. I either case the last name would never match. I have worked with civil liability union when living in Florida. And they take up causes and file class action law suit.
