Drawing upon a relevant example, when I tackled a similar issue at Gavi's Fast Food Restaurant, I listened to the feedback from customers about the confusing payment line and resolved the situation by implementing floor markings to direct customers appropriately. This action not only eliminated customer complaints about line-ups but also allowed our team to serve a higher number of customers more efficiently, ultimately enhancing the overall customer experience.
