How are you finding using a food bank?

Hello and apologies if this doesn't fit the No Stupid Questions community exactly... I'm working on a research project in the UK, around food bank usage, and wondered if anyone who uses a food bank would be prepared to answer a few questions...

1. Are you able to get enough food, toiletries, items from your local food bank?
2. Do you have any allergies or illness that makes it harder to use a food bank? ie. they never have any gluten free bread, or everything contains too much sugar
3. Do you care about branded foods versus non branded?
4. Are there items you can never find or are in very short supply at your local food bank?
5. How were you referred to the food bank?

The research project we are working on is looking into all aspects of food banks from someone deciding to donate, to storing the donations, to people receiving them, and seeing if there is some way to improve what is being donated and/or the quantities.

Any help answering these questions would be really helpful 🙂
