Communication device etiquette note

Yesterday, while I was in a hospital waiting for paratransit after my appointment, someone decided to type on my communication device without any prompting from me that it was OK to type. Don’t do this. And I don’t mean speaking to me, but something to show that you want to use it. Not just shocking me and suddenly you’re there typing right away.
