I remember thinking that Just-Eat.com were criminals for taking 10%.
Hungry.dk takes 1-2%.
You're most likely not being fair with what services these platforms provide, or how they structure their fees.
Wolt and other companies like UberEats or Postmates are food discovery, delivery and PoS platforms (and more). They don't operate on any single commission model.
(Ofc one could argue this pricing complexity is intentional so that comparing is more difficult)
