if she has no direct experience it needs to be translatable skills.
maths- she’ll need good mental arithmatic for drug doses etc. in her cafe work presumably she calculates change etc?
working under pressure- busy shifts, managing multiple requests, keeping calm, diffusing issues if customers are waiting. Understanding that working calmly and methodically gets the work done quickly with fewer mistakes.
working accurately and efficiently- when it’s busy it’s sometimes worth taking a moment eg to get an order right than rush and have to take more time putting it right.
h&s- has she done any training on stuff like chemical dangers and first aid- burns, eye washes, decontamination? Glass cleaners/beer line cleaners/oven cleaners can be very toxic.
Then your basic working as a team. Allocating tasks, deciding who does what etc. making sure everyone knows what their part is so nothing is missed or duplicated. Same with working independently- taking the initiative, working without direction etc.
there’ll be plenty, although I do agree Red Cross volunteering or similar would be good. Has she tried Samaritans? MH is massive now. St John’s ambulance as well.
I’d suggest a police ride along as well if her local force do it. Get a feel for the demands on emergency services as a whole.
