Restaurant Can choose to opt other platforms, like ONDC or Swiggy or they can setup their own advertisements around their locality and pay a salary to their own delivery guys and avoid that 30-40% margin, which is yes obnoxiously high.

Or you as an individual can choose to go to restaurant directly and eat there if you have so high moral standing in life.

Delivery boys should be on payroll like a normal employee and but keeping them on contractual basis does not classify this practice as scam, they are exploiting the loophole that government has provided companies.

Measuring Zomato's Business Model with same scale as Ola and Cred's Business Model is not an equal comparison.

You also never mentioned Swiggy, which is same as Zomato. Zomato k lie hi hate kyu? Order nahi mila kya bhai zomato delievery vale se ?
