There are plenty of carriers (some might even say all of them) today without standing places where you don’t have to pay for using the toilets and many of them are profitable. You don’t need to accept ridiculous things for that. It’s just that every time, one of them will try to squeeze just a few more cents out of you and if the public allows them to do that, all the others will jump at the opportunity.
You'd love it, if it were not for the fact that they went bankrupt in the 90s when the first low-cost carrier entered the Brazilian market.
