I’ve worked at many bars and restaurants. The best ordering interface I ever used was at Pizza Hut circa 1999. It was a monochrome TUI (orange). It was ancient-looking even then.
The speed was incredible once you got proficient. Once you got the muscle memory down you could punch in any single pizza order in less than a second. Even something complicated like different toppings on the halves was NBD. Pizza Hut was always coming up with these ridiculous gimmicks and the system could accommodate them seamlessly. Just incredible.
This system probably quietly saved the company millions in its time.
I pointed out that it would be far more cost–effective to simple let us request hard copies of whatever books we wanted, and then they would just stay in the library. No one worked remotely at the time.
We ended up getting Safari subscriptions for everyone.
