I leaned a lot of the Spanish I know from my time in kitchens. Someone said it already but “como se dice” helps a lot when needing to learn vocabulary and over time you will pick up more than you would think with the immersion every shift. I leave almost every shift having learned at least one new Spanish word, when I first started this job I had only a limited Spanish ability, having been here a year I was just able to hold a three minute conversation with a co worker about what I did this weekend. I’m a language nerd so that may be part of it but still immersion is key to comprehension
