Ok, so back on topic. I do think a chanel bag might be a bit extreme.
But, I have done larger items. Baby baskets, get well basket (with blankie, books and mags, snacks, etc) for a SA that had foot surgury. I regularly do chocolates, gift cetificates for near by coffee or starbucks, fruit baskets (for whole store).
I usually do it, when someone (my reg SA or another one) goes out of their way to help me, ie: track down hard to find item...bumps me up on the wait list (when I have procrastinated) that kind of thing.
