I had the opposite problem lately. Went to a naice shop and wanted to buy two different scarves, both from the same designer.
Shopkeeper: Are these a gift?
Me: No, just for me
Her: Well, I'll wrap them up nicely for you
Me: Thank you
So she takes the first scarf, removes the price label, folds it, wraps it in tissue, places a sticker on the tissue to keep it closed, pops it into a (lovely!) bag, adds more tissue that gets pouffed up, ties the bag with a ribbon, and puts it aside.
At this stage, she takes the second scarf, removes the price label, folds it, wraps it in tissue, places a sticker on the tissue to keep it closed, and reaches for a second beribboned bag.
I say "oh, no need to two bags. It's fine to pop it in with the other scarf". She looked at me like I had two heads and brusquely responds "I can't do that- the packaging is part of the philosophy of the brand".
I felt like Alan Rickman at the jewellery counter in Love Actually.
