Advice to Ubereats

This is more intended as advice rather than to take Ubereats to the cleaners.It's an open secret that food is way more expensive on any app than instore(The full chicken I ordered yesterday was R135 on the app but is R95 instore at Astagos). Smart consumers download all 3 apps(Mr D and Dryvar too) we compare the same food on the app and also on the restaurants own website(so we can minimize the rip-off). We then take into account your service fee and delivery fee. Personally I will only order from you when you bribe me with a large promo because I am aware that you use the High-Low pricing system. You are in esscence giving me a discount off an alreadly inflated price. Plus you have let to add on your mysterious "Service fee". What service it it for exactly because we are already paying a delivery fee and you take a % of the sale from the restaurant hence they have to charge more for the items they sell via you or it will cut into their margins. Switching from High-Low pricing to Everyday low pricing is very difficult but not you have created a situation in your business model where people time you and only buy when it makes sense to on your site.
