Since the corona pandemic I have been using mostly my credit card for payments. In 80% of the stores I paid with cards, but there are still some small stores like the bakery where it's common to pay with cash. Also there are still some people in my country who have no bank account or credit card. I think we will see a shift towards a cashless society more and more in the next year, but to completely stop using cash we are not ready yet. It's going to take some more time.
I also use credit card for buying groceries.
Its more convenient for me and less hassle because the line for those who will pay cash and credit cards are different. But since the line for those who will use credit cards are few, its fast to get done. Nevertheless I think going cashless wont be easy to people who used to fiat, specially for small transactions like buying a portion of bread in small store.
In terms of conveniently, no wonder credit card is the most on top for cashless transaction, especially we know that bitcoin is that popular for groceries or common stores. But in our situation now, physical distancing is utmost need, I think cashless--whatever form this may be- can help us a lot to prevent from getting virus. But to understand the small time business we need to consider, maybe exact amount will do and help you too away from the virus.

But to be honest using bitcoin for small transaction will make your headache.
