When I was at Bal NY this past January, I had my ponyhair work with me. I had put it down on one of their rock/sitting area to try on a French Blue work...next thing I know, I turn around to see two people petting it!!!
And another, I was at Barney NY. Again, I sat my Black Weekender down to try on an Ink Shopping. A woman grabs it and takes it to the counter to pay for that bag in a matter of seconds. She carried my bag to the counter - it was full of stuff!!! I had to tell her that it's mine. And of course she asked as to why the leather was so different. - it's an 05 bag.
Yeah, I'm notorious for leaving my bags around as I shop. My Barneys SA actually carries my bag and follows me with it (or she sits it right at the counter and keeps a close eye) - she's more nervous about me losing my bag than I am.
I'm glad you got a Balenciaga - don't worry you'll get compliments, endlessly.
