Yes, very strange indeed. Especially as I was ready to buy it and this really ruined her - well actually her colleague who had been helping me the whole time - a sure sale. Her colleague, my SA, admitted not to know about the issue himself, but he was quite young and new (some other SA even asked him about his name in front of everyone, even though he wears a name plate, d'uh), so I didn't really get a second opinion in the store. The SA, who warned me, actually immediately suggested the GST would be much better for my needs - however I really don't like this bag. Maybe she was just gambling, hoping to get me hooked on the GST? But that I would expect at a bazar in Cairo, not quite in a chanel store on Oxford Street, lol!
Really relieved to hear your positive shoulder report though!
