"Supermarket fixer" to go with Caffenol???

Do you have any idea

You don't seem to understand. I would never suggest anyone develop film in whipped up coffee developer in a hotel room. I would never suggest that someone soak it in table-salted water for a day to fix it. I would never suggest that someone let it dry, unfixed, and fix it when he or she got home. But this is about what someone can do. There are only three truly sensible alternatives to bringing the film on the plane: (1) get it developed before you leave, (2) bring developer and fixer with you, and (3) mail the film from and to your home. I, personally, would mail it. But this thread is about something someone could do - not should do.

Again respectfully, this is scientifically 'dangerous'.

There is nothing dangerous about it. I have a little test going to see what will happen. No one should try such a thing without knowing it would work out.

From some random online source: "The production of Na2S2O3 can also be accomplished by the boiling of aqueous NaOH (sodium hydroxide) with sulphur." Seems like you don't need the onions that much. Just gotta buy some sulfur and lye. Used to be able to buy big jars of sulfur at any drug store.

I used to get lye at the grocery store, and you can probably still get it at the big box stores (what I have in my darkroom at present came from Amazon, however). Garden stores sell "dusting sulfur" that's pure enough for the folks who make gunpowder with it. I wonder what the yield is on this? Obviously not something you'll want to make in aluminum or glass (hot lye solution will eat both); cast iron seems a likely candidate to stand up to the process.

I miss Gainer. He’d be perfect for this thread.
