Costco & Whole Food stores have especially declined in overall shopper experience. Clueless store staff, shoddy inventory levels, incompetent employees who cant be bothered to educate themselves on elementary details, rude and crass shoppers, shoppers who dont return their carts to the corrals, thinning variety of offerings, long lines at checkout, lack of adequate number of self checkout terminals .... the list goes on.
I recall even 3-4 years things weren't so bad at these two very different stores. Now they're almost uniformly bad.
I just wish they had large refrigerated silos outside the store in the parking lot, where they could let you pick up your online orders like Walmart does.
