if you're jumping on a call with someone (assume minimal notetaking if any required) and they ask to do audio-only so that they can walk while talking, would you be:

a) frustrated
b) indifferent
c) happy
or something else?

depends. 

nonverbal part is useful when the situation is volatile or unknown. if i know the person and i'm comfortable with the context, audio-only is fine.

i don't care about their reason, but i tend to subconsciously think less of them if they tell me and it's one of the current things™ (like walking now)
