Unfortunately, for the scenario I was replying to, a lot of the times when you’re doing support, you can’t see the user’s screen and are limited to verbal communication, so verifying what they typed or the output can lead to just as many problems. Any support scenario where you’re talking the other person through a series of tasks will be very dependent on how familiar each person is with the task you’re supporting. And no one Rs TFM these days, if you even get one.
I used to think there was nothing more stupid in zombie movies than uninfected humans just leaving each other alone and killing off the zombies. Why would you bother taking guns from other people when you have so many just lying around after 90% of the people died? If everyone just killed 10 zombies, the whole thing would be cleared up. I don’t think that anymore.
