Reading through these posts and descriptions defending food delivery; "Too hot, high pollution, bad traffic, crowds, filthy streets..." makes me wonder just how horrible it must have been back home for this to have been a consciously made upgrade in your lives.
For the OP - If you've a mind to sit and think for a moment, pretty much NONE of these delivery services were even in existence precovid. Basically the only food delivery was from the bigger fast food chains. Once covid hit and the world shutdown, restaurant owners needed to find a way to adapt to survive or go out of business. This brought about the new app services of Grab, Food Panda, etc. staffed by people willing to "risk their lives" so the world could eat and NOT be restricted to a steady diet of "fast food".
As a result, many people were not forced out of business, many people did NOT lose their jobs because no one was allowed to go out AND it increased exposure to many restaurants people had never patronized before.
As with most things you are forced to do, people got used to ordering delivered food from a vastly expanded menu of choices. Many still do because of laziness, convenience or just new exposure to variety.
Try and keep this in mind the next time you're whining about waiting an extra few minutes to mac on your chicken leg or burger with extra cheese. These drivers and apps kept that business open so you could.
