The tricky part is this: Restaurants want to serve people in-house. They want to fill seats with people enjoying a solid experience. CityTins has a "Dine-In only" clause on our coasters because it truly makes a difference for the restaurants. They profit from diners dining in.
Having said that, we all want to support locally-owned venues—especially now during the pandemic. If coasters are used for curbside, take-out, or delivery (if allowed), it really gouges the restaurant's bottom line and most cannot afford to honor coasters in this way. That doesn't mean that your support by ordering take-out doesn't help; it does! It helps restaurants to maintain and stay afloat. While they do not necessarily profit from these transactions because of the cost of doing business this way, they do manage to keep their doors open and avoid permanent closure in the interim.
