A GFCI, yes, but regular circuit breaker won't stop it from killing you, it's primarily there to keep the house wiring from melting and burning down the house :) You just need 6 milliamps across the heart to f you over.

This is what I had in mind: https://youtu.be/1RBwoUbvxx0?si=nbB6QCWywreHJdGF ...may not be an actual toaster, but pretty damn close

Breakers work when you draw too much current through the circuit and a metal strip heats up, expands and flips the circuit off. It's meant to stop you from plugging in too many devices and heating up the wire inside of your wall. It takes a bit of time activate.

GFCI stands for Ground Fault Circuit Interrupt. If any current is detected going across one of the current carrying wires and the grounding wire, it immediately turns the circuit off.

PSA, please, please don't rip off the grounding prong on your outdoor water fountain pump because you can't find a grounded extension cord.

It depends honestly. Here in the states, we GFCI kitchens, bathrooms, laundries, garages, crawl spaces underneath houses, and exteriors, basically anywhere it could be reasonably expected to come in contact with water or an unexpected grounding/earth source. From there, you can either do a GFCI breaker or receptacle. Both will protect everything downstream from the device, but the choice comes down to convenience of operation. I'll generally do GFCI breakers for dishwasher, disposals, refrigerators, etc, just so that if the GFCI trips you can reset it in the panel so you don't have to pull the equipment out to get to it, but I'll do kitchen and bathroom counter convenience plugs as a GFCI receptacle (and daisychain all downstream kitchen receptacles from the GFCI receptacle) to be able to reset it right there at the point of use.

You could in theory GFCI protect an entire house/flat, but it likely comes down to cost saving and avoiding nuisance trips. Motors as they age tend to leak current and trip GFCIs, and any number of delicate electronics can be finicky, so that's typically why we only use them in wet locations.

Hair dryers have killed people too, which are much more likely to be found in a bathroom. It's why they all have GFCIs in their plugs. I've also heard tell of a girl who was electrocuted in the bath by her phone charger. The USB cord won't do it; the 5V USB puts out can't hurt you. But if the charging brick and 110V wall power cord you've plugged it into falls into the water with you you're gonna do the 15 amp dance.

The shopping or the rum?

Both worked wonderfully.

Made some white rum. (Nothing to it)
Some dark rum. (Added Torched Oak™ in bottle - we developed a neat technique to speed up the barrel aging without barrels)
Some spiced rum. (All the things)
Some over proof rum. (98%abv straight off the coil)

That's why there should also be an extension cord in the cart

Well, not specifically for toasters. It was more about hairdryers and curling irons causing accidental electrocutions than for suicide prevention.
