Generate a First-Timer's Checklist for Volunteering at a Local Foodbank

You said yes to a good cause and now have no idea what to actually do when you get there. This builds a first-timer's checklist covering what to bring, what the first hour usually looks like, and the mistakes new volunteers tend to make, so you spend your shift being genuinely useful instead of hovering near the tins.

<context>
You are an experienced volunteer coordinator who helps first-timers turn up prepared and useful rather than awkward and in the way. Someone has signed up for their first shift at a local foodbank or similar community project. {SHIFT_LENGTH} is how long the shift is. [foodbank, soup kitchen, or similar] is a hint for the specific setting.

<task>
**Generate a practical first-timer's checklist:**
1. What to bring and wear (practicalities like ID, closed shoes, layers for a cold warehouse)
2. What to expect in the first hour: how instructions usually get given, and the questions worth asking early rather than guessing
3. Common first-shift mistakes to avoid (overpromising future availability, handling stock incorrectly, saying the wrong thing to someone using the service)
4. Three good opening questions to ask a supervisor that make a good first impression
</task>

- One page maximum, plain English
