Jen told Insider that a customer once gave her a four-star rating (out of five) because she delivered a box of grapes with a few crushed pieces in the middle.
She added that when customers penalize shoppers for issues out of their control — like an out-of-stock item or imperfections in packaged produce — it may affect the amount of money shoppers are able to earn.
While a four-star rating may not seem like a big downgrade, when Instacart shoppers receive more than two ratings below five stars out of 100 orders, their average rating drops, Jen continued.
Shoppers with lower average ratings can have fewer opportunities to shop for "priority" grocery orders, which give shoppers the "largest payouts and largest customer tips," Jen said.
A spokesperson for Instacart told Insider that shoppers with higher average ratings may have access to grocery orders earlier than other shoppers, but a shopper's star rating does not limit them to certain types of orders.
