As a former Uber engineer I did the employee delivering program a couple of times (pre-covid) and it was really eye opening. I’m based in Amsterdam so cycled on bicycle to make deliveries - it’s hard work, but also was a great way to explore the city and discovered some great eateries I wouldn’t have gone to otherwise.
I still remember a story about being yelled out of a restaurant for coming in to pick up a delivery. The restaurant owner set a message to couriers in the app that instructed us to wait outside for the pickup, but I didn’t see it because the text was so small. Instantly filed a bug report for the Driver app team to make the messages easier to read!
