I've never ordered through one of those online restaurant delivery services and don't have any of the apps. I've also never used any of the grocery delivery apps, as I prefer to shop for myself and pick what I like in the store. I've heard of Lyft and Uber, but have never used them either. I just have an issue with some tech company making billions of dollars off the people who actually put up the cash to provide the goods and services.
I will order online through the restaurant's own site or, old school, call the place to put in my order. I then get in my car and drive there to pick-up the order. There is usually a lower cost on pick-up orders plus the food is ready much quicker. In addition, there are no service charges for the delivery service and no tip or waiting and worrying that it gets delivered to the wrong address.
