None of the bags I've purchased in the EU came with the sales tags, maybe they assume everything is already listed on the invoice & VAT refund document? Even some of the bags I got from the US boutiques don't have tags, only the two where I purchased from Bergdorf and Neiman have tags.Both in boutiques in UK and FR (flagship) the tags were taken off and not provided. Surprisingly the one in FR the SA placed it in an envelope .
Edit:
Came across some threads in TPF from 2018 and seems to be normal and for inventory purposes, but the practice varies from location to location.
