<grin> I doubt it but thanks for the thought.But you can't be sure she was your client - maybe she was just flirting
ETA: maybe the card found its way there via someone who picked it up in a different coffee shop and thought it was a nice thing to do anonymously. Or maybe it teleported. Or you've lost your memory and haven't realised yet.
No, you must have misunderstood me, this happened in the same coffee shop where I'd been previously and left my card. She most likely cleared my table after I'd left the first time, and pocketed my card.
I just thought, how often we disconnect between our internet world and our physical world. It didn't occur to me that she may have been the client that picked up the card from that table until well after I'd left.
