Milan is easy to walk through so I went to the Decathlon near the Castello Sforzesco. A man at the door stopped me at the door speaking too fast for me to understand his Italian. It is the era of COVID so I figured I had to wait. 30 seconds later another man rushed up to me and quickly took my temperature and then let me in. This place has everything from camping equipment, to bikes, to Pilates, all kinds of gear and super well organized. I had no trouble finding everything I was looking for. I went to the automatic check out and a super friendly assistant helped me navigate with a little English and Italian mixed in. They don't take American Express but I was able to use Apple Pay and my N26 debit card. I left having a super easy shopping experience. And they have lots on sale.
