It's not. If you were at the restaurant, you'd tip the server. If you were home, you'd tip the deliverer. If you picked it up yourself, why then you could tip yourself :)
> you're using to tipping at a restaurant and never questioned it
Now that's a bold assumption :) How about, tipping at a restaurant is part of the culture, and many people do so begrudgingly?
Dissecting this meme reveals that people are comfortable tipping for the act of waiting on them (the so-called service). The person who cooks and the person who bundles supposedly serve the institution, and so they should be paid by the institution.
Or so it would seem. The waiter and the driver also ultimately work for the institution, so one could argue that they, too, should be paid adequately by the institution. Tips should be reserved for exceptional service to you beyond what they're expected to perform for the institution.
So if the cashier at the takeout place made you happy and you wanted to tip him/her for that... you could knock yourself out. It's worthy of tipping because you felt like it.
This does not match my experience at all. You may see tip jars in those places, but there is never an expectation (in the soft-obligation sense) that anybody tip into any tip jar ever. The only place where tips are considered soft-obligatory are waitresses and food delivery, and in those cases you leave the tip on the table or hand it to the person yourself. Tipping into jars may be desired but is never expected.
Are you perhaps an immigrant to or tourist of America? I can see how foreigners might get confused by the tip jars and not pick up on this nuance since it isn't explicitly spelled out anywhere on the jar, but I don't think people integrated into American culture perceive any sort of obligation to tip into jars. If you sit in a shop and watch people order, you'll surely see that the overwhelming majority of people never put anything into the jar.
(From what I have seen in Canada, all of this is true there as well. Tips for waitresses are socially obligatory, while tips into jars are not.)
I don't think tipping on those screens is considered soft-obligatory in America, but maybe I'm guilty of a few social faux pas in Canada..

What about taxis? I've been harassed by taxi drivers when I forgot to add a tip because I've not been in a country with tipping for a while.

I don't know where in the US you are but every time I'm in california all the electronic payment systems (essentially an Ipad running some special software) ask you for a tip when paying by card. The minimum selection unless putting in manually is usually 15%. I haven't seen a top jar in the US in ages, they are very common in countries without tipping culture like Australia and NZ (funnily enough I feel much more inclined to put something in those instead of tipping in the US).
As a European living in the USA, the distinction always seemed made up for me. If someone delivers a take-out order, why is that less worthy of tipping, than if you're in a restaurant? What about the person who bundles the order together for delivery? What about the person doing the cooking? Etc etc etc.
The answer is that you're used to tipping at a restaurant and never questioned it, but when some other tipping is introduced you rightly recognize it as an abuse.
