How I handle Returning expired milk Without saying a word.

How I handle Returning expired milk Without saying a word. Returning items is a nightmare. I get terrified of blocking on dates and numbers while a line forms behind me. So I generate the script beforehand with my app. I walk up to the counter, place my phone down with confidence, and lightly touch my throat. Because the screen covers every detail, it usually gets done in one go. The problem isn't that I can't speak well. The problem is failing to communicate. This is my solution. What is yours?
