I know you differentiate between locals and foreigners and how they are treated.   I'll accept that as a reasonable point.

However, when I visit Dominican or Mexico, the standards are much lower, hotels cracked, dirty, falling apart.   Nobody smiles at me and they all expect tips for doing a shitty job.

In Cuba, the customs officials ladies even flirt with me when i speak spanish with them, nobody expects tips, not allowed to ask, and everyone smiles and goes above and beyond in their job.  Things are dong to a higher standard and properly.

You get a sense of a non-degenerate society.

This makes me want to tip them.  Then I go to the poorest neighbourhoods I can find in cuba and give them all my old clothes, some money, old technilogical items.

In those poorest neighborhoods, nobody is homeless.

I've only seen one person in Havana who looked homeless, even though he wasnt, just a hardcore alcoholic. 

 Bro, they do it because your tip is more than what they earn in a month for their salary, they eat thanks to your tip that's why they make an effort to earn it... from other countries I can't give much opinion on the service, I've been through a few and it seemed similar to me everything in general at the service

There are homeless people too... I have seen several die on the street, even from not eating... but we return to the same thing: I cannot put that on my death certificate because they punish me at work... in other countries there may be more or less: I don't know. My point is the same: the government lies too much, extremely 

 Bro, all governments lie.
Many of them more than the Cuban government.  American government especially.

Have you seen the president of the United States on television?

They think they are the ones who defeated Hitler too lol 

 Bro, my tip for mexicans and dominicans is more than their monthly salary too, by more than in Cuba.

Yet they frown and grimace and demand the tips and fail to deliver quality service.  I felt like i was being held at gunpoint.

Not to mention the abductions for organs in Mexico and Dominican.
