> I don't see what problem the OP has

OP's problem seems to be that there is an assumption that they are okay with being recorded, which is their very first argument in this article. What's more, with the attitude you apparently have, we should expect more incidents such as this:

This whole "it makes the flow of the appointment much better" argument is one that I assume you'll use to justify this default position of recording others without clear consent. Clear consent, mind you, is receiving a "yes".. as opposed to saying "they didn't say no".

Consent doesn't happen just because someone didn't say no.

> If someone asked me not to, I'd turn it off

Case in point.. you've admitted to recording before receiving affirmative consent.
