Force yourself to read slowly and doublecheck every order. If anyone gets pissed at you for it tell them youd rather get it right and not make a mistake. Sometimes what ill do is i like.. train myself to emphasize on the different sounds? Like "WHITE mocha" or "ICED drink" You can try to like associate a color or a familiar sight to each, so when someone orders iced drinks you just picture it as being blue/a frozen lake and keep that image in ur head while making it

Reading this really helped me. ❤️
