I don't work here.... but he does
A few years ago I shopped for InstaCart for about two weeks before I got fed up with it. One day I was shopping an order at Publix, and the customer had ordered a couple of cases of a specific soda. That soda was on sale so of course the shelf had been completely cleared of it, but luckily there was an employee in the soda aisle so I asked him if he could look up if there was any more. He pulled out his inventory device thing and was looking it up for me when a woman came up and with no "hello" or "excuse me" asked where the juice was.
The employee did absolutely nothing to acknowledge the woman, so after a second of awkward silence and her staring expectantly at me, I said "um I think it's a couple aisles over, I believe on aisle 7?" She wasn't impressed with this answer and went "you think? you don't know?", which made me realize she thought I was also an employee, and clearly not a very good one. I told her I didn't work there, and, pointing at the employee, she went "well he does! and he's not even acknowledging me!" The employee looked up for the first time through this whole interaction and immediately snapped at her, saying "I can only help one person at a time, and I'm clearly helping this person right now!"
The two of them had a back and forth where she told him that he had bad customer service and should have at least acknowledged her when she initially approached, and he defended that he was obviously busy assisting someone else and she needed to wait her turn. I just stood there dumbfounded waiting for him to find my soda, thinking about how they were both kind of right but also so unnecessarily rude to each other.
