Technically...you can use other parts of a push door other than the plate...some door handles(the lever types)...can be opened by the side of your hand...and you don’t have to grasp the handrail(unless you have balance issues or strength issues)....suggest using the 2nd joint of a curled finger to punch in your selections....or a stylus...
GERMOPHOBES UNITE!
These days, I mostly interact with my phone via voice. I can no longer be bothered to type. Plus, it's a kick to see the wrong text briefly appear, then get corrected, and then the answer appears, all in less than a second!
The hygiene problem can be solved by voice ordering. Just like the drive-thru. Only with silicon on the other end (in both cases).
are you as worried about the person handling your food? How about the ticked off person actually making your burger. Worried about them spitting in your food?
Germophobes unite alright, stay at home and fix your own food.
