The Land of Smiles, they call themselves

Thailand is a signatory to a World Trade Organization agreement that forbids dual pricing for the same service based on nationality or race. Currently foreigners pay up to ten times as much to enter a national park as do Thai citizens.

I am currently unable to swim in my local swimming pool, for which I pay a yearly fee, because only Thai people are currently allowed to swim. The Covid-19 Pandemic is offered as the excuse for this discrimination.
