My favorite is when you tell them "your app says it's in stock with 58,837 units but there's none in the section they're supposed to be" and then the employee pulls out their own phone, opens the same app, and says "well they should be in [same aisle you just told them didn't have any]. Did you check there?". It's to the point that if I ask a question and they pull their phone out and start to open the app, I just walk away. They're useless. But I guess I'm a clown for expecting a service worker to provide the services they're paid for and not just tell me to "check the app".
