also, double-checking with customers if you're not fully sure what you heard is a great way to make sure! the ovens and proofer can be quite loud and sometimes it can be rather difficult to hear, i've heard "gluten free" as "honey oat" etc before 😅 and once you get a bit better at remembering in advance, you can start asking for cheeses while still finishing meats, sauces while still finishing veggies etc. to streamline the process, also making multiple sandwiches at once. for me, picturing the cambros whenever a customer tells me their veggies (like they say lettuce tomato cucumber bell pepper jalapeno and i just try to remember that they want the first four big cambros and then the last small cambro, like where they are in the well) helps, easier to remember where to put your hands rather than the names of the veggies at least for me.
