Big chain stores suck! Be it petsmart, petco or what ever. These places ruin the pet hobby for many people by selling unhealthy animals and giving out bad advise. They will just about hire anyone with out serious if any knowledge about animals. These unknowladgable people are now the "experts" that novice people go to for help. It is freeking pathetic.
Even the rare truly knowladable employee can't be as helpfull as they would like to. It will hurt sales when you tell people to not buy a fish or don't buy (insert what ever product) because it won't help.
It is such B.S. the garbage I hear just about every day that the local chain store in my area tells people to do. THings like, "your water quality is bad, buy this product and it will fix it" or If you add this product to your aquarium, you will only need to do one water change per year" (i really do hear that) or 1 fish per gallon. All these things help the stores sales, none of these things help the customer.
Did I mention I hate these places?
