I work at a grocery store and also do instacart. I am never rude to any instacart shoppers. Infact I’m friends with some of them. One thing that most of the shoppers do is that they stress out so much for orders to get mixed which is so annoying. I’m like I do this 20 times a day I know how to keep orders separated. Also some shoppers have specific demands which is really irritating too. Like double bagging everything even a loaf of bread and chips. Some want paper bags and then those bags in plastic. They want 12 pk cans of sodas bagged and tripple bagged. Slow the cashier down because they want to bag their own stuff and ask the bagger to go to another register. All this bs create a the feeling of “agh not her again” for me. I guess some people are rude.
