Toilets in many third world countries are apparently not capable of handling paper and clog easily. When I first bought a rental house I had Mexican tenants who used a trash can for toilet paper, until I let them know that unless you stuff the toilet with large quantities it would not clog.
You may not have been specific enough, after reading about the "rest of the story..."
I have a close relative who moved to Costa Rica a few years ago. I will not provide identifying details to prevent possible embarrassment.
Costa Rica is a wonderful country, and a small percentage of it is functionally a "first world" country. The remainder is firmly "Third World." Consider that the Capital, with 334,00 people
This jammed, solidly urban environment is serviced 60% by septic systems most improperly built or maintained. Half the manhole covers in the city are missing, stolen. Yes, even those in the middle of major intersections!
My close relative built a gorgeous Villa a few hours north of the capital, on two acres, within a golf course. A 5000 two story sf house with a rooftop terrace, a huge swimming pool, a separate, smaller 1200 sq ft "guest cottage," and a total of 7 bathrooms. All on the septic system!
All the bathrooms, two kitchens and the Pool area Cabana-Professional grade BBQ and Bar all use the Septic system.
And all the bathroom solid waste is collected in small waste baskets, gathered daily and collected in a large bin in the garage, then dumped at a remote location once a week.
Costa Rica does not use what we consider normal toilet paper; What there is in tourist hotels and the few families who insist on it must be imported.
To respond to the "paper" issue, as far as I could tell, they have not even heard of "Septic-system" grade toilet paper.
So it's not a big surprise that the fourth world koranimals find it impossible to adapt to the civilized European environment.
To rational people, that should be a cautionary tale...
