Purchased a 9.5 inch Crepe Pan ( Anolon ) it had a little round sticker in the middle of the pan. It took about a 1/2 an hour to get that sticker off. Boiling water with vinegar, scraping with a rubber spatula. The glue got to the edge on the pan stuck there. In all your reviews no one mentioned it. How is that possible? Did I buy the one pan where that glue was used? Very disappointed. Please reply.
