This store needs a vacation. Everything looks tired. The automatic doors squeak. The floor is uneven, unpainted, and unclean. Even by the standards of big-box stores, this place is lacking. It is worn out.
That said, they'll probably have what you need. All of these enormous pet stores stock the same goods, with only a few exceptions. If you are buying the same bag of dog food every couple of weeks it probably doesn't matter what the place looks like. I don't avoid this store, but it sure doesn't have the clean, cheerful feeling of a Petco.
