Worst “trick” I have tried to use is for people who have the same name as me, or my brother, or someone other person who is very close to me: “oh great, that’s my name too! Now I won’t have to remember a new one!”. We laugh and high five.
Of course, then I don’t retain any association with their face and it fails spectacularly next time I see them.
Probably object storage, like s3 or similar
