i need advice. i just starting working at a cafeteria, and i basically have no idea what the cooks write on the slips they give to me. i haven't learned yet, and they assume i know. and their key system on the till is very awkward, and i've never worked in an environment like this before. however, they are cutting off my help after two shifts and making me go on my own tomorrow. how do i tell my boss i need more training and help?
