The Lowe's item is completely different:
One it has not even gone into court - so you can't even determine whether it will result in anything. Also the difference in this case, is the worker had on protective gear and was using equipment that requires safety gear, but yet was working near where customers did not have the option for safety equipment. Your situation is not a loud noise which would require safety equipment.
You are comparing things that are not comparable.
As we have repeatedly asked - have you been served with any sort of notice from the courts? If you have not, then you have not been sued.
And Justin Beiber actually won that case so it shows it is unlikely that someone would be able to win and unlikely a lawyer to take such a lame case as you describe.
Did you talk to a counselor yet?
