I spent two weeks delivering for Uber Eats and made $4.40 per hour

What about tipping in Sweden? Do you tip the couriers that deliver food to your home (and what would be an average tip)?

I don't think tipping is very common in Sweden. I live in Norway, just next door, and it would never occur to me to tip a courier. It's unusual to tip in restaurants here too.

No, we don't tip couriers in Sweden. Tipping is almost done at restaurants and very few other places/situations.

Wouldnt that just push the "guilt" to the consumer?

Wikipedia has good information about tipping customs and laws in countries throughout the world. Here's the Swedish entry [1].

As a rule of thumb: apart from the English-speaking countries in EU, tipping is not mandatory.

It's not mandatory in the UK either. It's certainly pretty common in restaurants, as long as they don't already add a service charge, but it's unusual to tip in just about any other situation.
