Bonus categories are designed to keep the card in our wallets so that we also use it for other purchases. They are not intended to encourage us to shop at a particular type of store. There are still many cards with dining bonuses. The pandemic has distorted bonus strategies because in many jurisdictions non-essential businesses are periodically closed. Supermarkets, takeout/delivery restaurants, gas stations (and some other categories) are typically exempt, and the card issuers want to encourage us to use their card when shopping at the places which remain open. Look again in 2022 to see a more normal array of category and temporary offers.
