It must be an SA thing. I seriously considered buying a second love bracelet and an SA screwed all the love bracelets on my wrist (all screws) and pretty much let me walk around to see how it was like to have multiple bracelets hitting each other. (I remember the bracelets being new too.) That's when I decided I would just stick with one love bracelet. The sound of heavy bracelets hitting each other was quite painful for me. Maybe that's why they don't allow people to have the bracelets touch at the store? So when you come home, you're like oh-uh..that noise is loud! Not to mention that even though they are the same size, the bracelets still go underneath each other (because of the oval shape). So deep scratches are more likely to form. Multiple bracelets look great on others, but it's just not for me.
I agree with the others, you should at least be able to see the love bracelet on you, not some steel one for measuring. If I were you, I would go back and talk to another SA. Hopefully the one that gave you a hard time is on her day off and won't be there.
