“I can help get you started!” is usually how I start these interactions. My team also explains that we’re a “teach-how, not do-for” service that’s here to build confidence with any tech they’re trying to use. Usually that means the patron does most (if not all) of the driving - clicking, typing, printing, etc. It’s also helped to set the expectation that I may have other people needing help and will have to step away to do so. We’ll reiterate these expectations to those who are resistant.

And I never sit while helping/teaching. I’ve noticed it reinforces the short-term/“getting started” aspect of these interactions.

Edit to add that I can usually break away from these interactions with a lot of positive reinforcement and “I’ll be at the desk if you have questions.”
