Emily Leshner and Leanne Italie Associated Press NEW YORK — In Miami, Oklahoma, restaurants and their customers are doing their part to ease pandemic heartache, one meal at a time. Cafes in and around the close-knit town in the state's northeastern corner have put up "receipt walls," allowing diners to pre-pay for meals and the needy to grab what they like, have a seat and refuel — judgment-free, no questions asked. The idea of providing free, pre-paid meals spread from restaurant to restaurant a few months ago. Many recipients are homeless or have otherwise hit hard times since the pandemic rolled into Miami (pronounced my-AM-uh), population about 13,000. Two February blizzards brought even more trouble.
