I guess your experience really depends on who is working at the time as I had a different experience than the 5 star review. I have been to several Pet Valu stores in the GTA and always have had memorable experiences.. except at this one.
There were two employees working at the time. One briefly asked what I was looking for and then told me where the items were, then left to the back room or something and was never seen again. The cashier was leaning on the counter on her phone the whole time and didn't even say anything as we were walking past leaving the store (empty handed).
This isn't particularly a "bad" experience it just is drastically different than ALL of the other Pet Valu stores I have been to. At other stores, the employees are genuinely interested in me as a customer and offer detailed information on products without me even asking.
