Anybody else dislike the "Do you remember me" question. I'm highly unlikely to remember anybody,  if it's been less than 3 visits. Do you just say, "Of course"!

I receive phone calls and emails years later, using different email address or different phone number asking if I remember John from Scotland with the nice smile.

99% of the time ill know if ive met them by their voice, it acts as a weird memory unlocker. Sometimes ill know exactly who it is or just have a vague feeling they were nice/easy/awful.
