Decent PetSmart location, substandard service though.
I recently stopped in with my girlfriend and her mom to help them buy dog food and Christmas hats for their dogs (yes, I know). Anyway, this is the store where they normally purchase all that from. The aisles are well-stocked, although I didn't see any employees walking around or helping people anywhere.
After finding what we needed, we headed up front to the registers. It took the two gals working there a minute to decide which one they would open, but eventually they did. My girl's mom tried to make small talk with the cashier and the girl totally blew her off and wouldn't say anything back. I found that a bit rude.
When we left, we realized she didn't add the coupon we gave her to the transaction. This prompted my girl to freak out and try to go back inside to give the cashier a piece of her mind. We convinced her it was too close to Christmas for an epic public meltdown, so she held off from doing what she wanted to do.
So to recap: no employees working on any aisles, rude cashiers who are inaccurate, but good products all-around at PetSmart. 3-stars. And I think that's generous.
