I knew it was going to be Tiffany's, though. Walking into their flagship store was an experience in itself and upstairs where all the engagement rings are (or were, at least), I even saw (a) Holly Golightly! Seriously.
I chose two rings and 'reserved' them. The sales assistant was polite but not super friendly or anything. He did ask for my boyfriend / fiancé's name before I left.
And the next day, we walked in. He recognised me, then looked at my fiancé. He suddenly became the most charming person ever. With a big smile, he walked over to meet us and addressed my fiancé by name. Maybe I should have been offended by this transformation but I was too amazed and impressed!
Another funny thing I remember is that every time we wanted to look at a ring by the big window (different lighting), the sales assistant had to 'inform' the bodyguard. Yes, there was a bodyguard standing by the window! Did they think we were going to jump out of the window with the ring?!
Now tell me your story! Did you know he was going to propose? Did you choose the ring with him?
Or how do you want it to be?
