I’ve always assumed you pay extra because multiple people have to carry the bag around after you check it, and that’s harder/more dangerous at higher weights.
In warehouses, you gotta go get your lift belt and often a partner if something is over a certain weight, and you aren’t covered by workman’s comp if you just try to do it quickly without those, so it’s a serious hassle.
Spanglish doesn’t mean 50/50 lol. And the “-ado” is absolutely pronounced the way they say it in Spanish, like dorado, tirado, girado, cerrado.
You’re making up random rules and limiting pronunciations in order to make this shower thought true, and it just doesn’t hold up to closer inspection.
