Given that I've had negative interactions with two employees of theirs now in the space of a week, I felt I needed to speak up. The most recent was yesterday afternoon at the Whole Foods in Potrero Hill. While grabbing bananas from the produce section, I ran into a woman blocking a narrow isle with her cart and talking on her phone. When I said "Excuse me" she glanced at me out of the corner of her eye, then proceeded to look away and ignore me as if she hadn't heard. A few minutes later I went to check out in the express lane with my bananas, and box from the salad bar and encountered the same woman again. She tried to push past me with about 20 different items in her cart, which I put a stop to, but rolled her eyes and ignored me when I pointed out the sign that said "8 Items or less". When she got to the next cashier, who politely scanned her goods despite the overloaded cart, I clearly overheard her tell them she was with Instacart.
While the Google Shopping employees I've encountered have always been upbeat and polite, Instacart's employees are as ignorant of proper etiquette when interacting with other shoppers, as Uber drivers are of the rules of the road!
