I expected most of the services to screw up on the avocado, that's why I made it part of the order. When the Postmate got it right we speculated over why. The answer we came to is that women are more likely to closely evaluate produce. After talking to some of the services, it turns out that women are overwhelmingly better shoppers. I assume this is because culturally women grocery shop more than men.
I would edit that into the post. Right now, "It's hard to say whether this was due to the startup or because the competitor was a female and thus had more attention to detail" sounds quite different.
