You do seem in an awful hurry. What is becoming routine for you is still new for a lot of people and you need to take to account that crypto is still illegal in a lot of the countries so it will take some time to make real your desires to pay with crypto in shops. Nevertheless I know about Paypolitan project (https://paypolitan.io/ ) that is working under creating an application that will enable quickly to convert crypto into fiat and then (using that app) to pay with it in shops. This might be a kind of transitory stage before implementing crypto as a form of currency by itself. Hope they will succeed and soon will have an opportunity to go to the shop with such app on the smartphone.
