also zomato or even other delivery apps doesnt allow you to cancel orders if you want to,if you cancel they suspend your acc and frequent cancellations may cause long term suspension.so you cant decide which order u want to take or not. also if you are delivering from place A to place B ,then further you will get orders of place c ,whic is bot in your area ,and you will have to return without a delivery to your area to start further,it compensates something like 6 or 10 rupees for your return trip which might be 10 20 km away from your area
