We have different delivery services in my country (mostly wolt and glovo), and yep, they fucked the prices of food here.
They probably take 20-30% of the item price from the restaurant (+charge delivery extra)... so eating inside or takeout should be cheaper.. but nope, to keep the prices consistent, pretty much everyone raised all their prices to the delivery levels.
I'm saying that stuff used to be eg. 7eur if you either picked it up or ate inside. Then wolt came, and due to wolts taking a percentage of the price, the price was 9 or even 10eur + delivery fee if you ordered on wolt, and because people complained (because the in-restaurant price was still 7eur), they raised the price to 10eur in the restaurant too.
I tried switching to Postmates today and was presented with 5 different fees including taxes, only 1 of which was actually covered by their subscription service. This is in contrast to Door Dash, which only had 3 fees (delivery, service fee, & taxes), which were mostly covered by their subscription.
So I have to hand it to DD, despite all of their flaws with transparency, they're a more transparent about fee structuring than some of their competition.
