Both correct in my situation. I will sometimes send a pic to seal the deal:
a) not that concerned about it in the first place
b) I always send a pic of me that’s already commonplace online, Facebook, IG, etc. my (naive?) thinking is I could thwart any attempt at embarrassing me as a client or whatnot by admitting “yeah that’s my pic...not sure how they got ahold of that”. It’s worked in the single time ten years a provider made a pathetic attempt to “out” me as a client.
