Accepting crypto at my small business - what have you used as customers and/or as a business?

I am the owner of a small business and I am interested in accepting crypto payments from my customers. My business is a drive-thru coffee shop so I need payments to be fast and can’t have someone holding up the line for 5+ minutes trying to make their crypto payment. I am trying to figure out what options have been used by other businesses and customers.

As a business owner, what crypto payment options have you used to accept payments? Which ones have you found to be the most user-friendly, fast and secure? As a customer, have you ever used crypto to make purchases? Which payment options have you found to be the most convenient, fast, and reliable?

Any advice, tips, or recommendations would be greatly appreciated.

Thank you in advance for your help!
