I think perhaps the misunderstanding came from the interpretation of "megacorporate". I am refering to the corporate practice of animal husbandry (specifically fish). I expect no more from the employees than I expect of employees at other retail establishments. Many of the employees are unskilled and simply need a job. There's nothing wrong with that. However, it is clear that petco does not have a corporate policy regarding the way these fish are treated. That is why each store is a new experience.
As far as making a complaint or being more proactive, once I have solved major issues such as human trafficking, world hunger, war, cured cancer, etc... then I will move on to seeing what I can do about these poor fish.
In the meantime, I would hope I will still be free to share my opinion on a local forum without being lambasted over misinterpretation.
