Whenever I give a break/lunch for Tech, I make sure I am well equipped with walkie and zebra. Even if you are just there to help with cashiering, guests will see you as an expert in Tech thinking you know everything. The zebra at least helps you locate stuff. As for walkie, I think it helps when you need assistance just in case you are by yourself and need to ask a question. Also, you would want to ask the Tech person for things that you need to know especially for the things that are out of stock or let’s just what to say when people ask you about the xbox and the ps5. Also, if you are not familiar with how to open secured cases/pegs with lock etc in Tech you may want to get a quick crash course how to open them. Also if a guest wants to see an item from the case (ipad etc) make sure you guard that item like a hawk.
