Is there a fat tax on any public transportation?
<|assistant|>
Some countries, such as the United Kingdom, have imposed a so-called "fat tax" on public transportation. This tax is based on the size of the person, and typically applies only to select services, such as first class seats or premium cabins. In most cases, obesity is only one of many criteria used to calculate the tax, rather than the sole determining factor. Additionally, these fat taxes are often nominal and do not typically cover the entire cost of the trip. Most countries do not currently impose a fat tax on public transportation.
