depends on the setting. At a lot of places like colleges or sheltered workshops and so on where people who suffer from panic attacks might be trying to get back into the swing of things, drinks aren't allowed in the main rooms. So a non-smoker starts having a panic attack and indicates they want to leave the room, a staff member/link worker/carer/call it what you will goes with them to make sure they're okay. By my reckoning, to make a cuppa, wait for it to cool to drinking temperature, and drink it, takes at least twenty minutes. If a college/workshop session is an hour long, twenty minutes is a bit much, and probably more than the person needs... and it then puts them at a disadvantage for the next session. Possibly sudoku puzzles are the way forward...
