How can i get a proof of purchase from Apple physical store

Found similar question here but it looks like that after few months it’s already impossible to write there, so here’s the new thread.

here’s the story:

On 19th of August I went Physical Apple Store on Orchard Road (Singapore) to purchase Airpods Pro. When arrived there i had to signup for a “product experience” first. Which I did (and i have a confirmation email of that) - when it was the right time I returned to Apple Store and went i side for a purchase. Eventually I purchased Airpods Pro and during the purchase session apple store sales person gave me the device to input my email address so that i would receive a receipt with purchase confirmation (and she suggested that in case of return / refund / warranty - i would need to use that email) - however, 4 days later and I still got no email or any indication of purchase.

is it possible to request an email confirmation for common sense needs?

Thanks in advance.

Artem.

P.S. - for some reason when i tried to select the other topic for this thread it doesn’t have anything related to Airpods Pro or physical store issues, or receipts - but it is obligated that once you click you must select something from their list. So i picked iphone x 🤷‍♀️ - i mean it’s not really related but since website doesn’t allow you to select select “nothing” - here it is.
