> airlines charge more if you're too large to fit your seat

I don't think this is a good example, because you're literally using more of the product that's being sold. I get where you're coming from but this one doesn't seem to really reinforce the point you are trying to make. It's like selling by weight or something if you wanted to compare it to groceries.

well there are valid and invalid examples, I don't think you could have a blanket rule that covers everything

with the airline seat example some could argue that they have health reasons beyond their control and it's not their fault that airline seats are so small (they really are smaller than ever)

another example are stories of electricians charging more to people who want EV chargers installed because they already paid a premium to buy the EV, contractors will often bump up their prices if a house looks nicer, etc... these sort of biases have been rampant everywhere for a long time

We can do some things to start with which I think would capture a lot of the downsides of these pricing models.

I've heard people work around this by getting a plug-in charger instead of hardwired. They get a 14-50 plug put in saying it is for a welder for their home workshop or for an electric range or an RV hookup for when their parents visit or something like that. A clothes dryer outlet works too, but usually won't support as many amps. All those, except the clothes dryer, still do give some indication you probably are reasonably well off or have well off parents at least, so might invite some gouging.
