In Thailand, we have our own numbers which are unique to the Thai language. However, you will be happy to know that when you are shopping you will nearly always see the price written using Arabic numbers. This means that you won’t have to learn how the numbers are written if you go shopping. Most shopkeepers at roadside stores have a calculator handy so that they will tap out the price for you. But it is a good idea to try and learn How to Pronounce Thai Numbers.
We are sorry to say that some tourist attractions in Thailand have a two-price system where they charge foreign visitors more than local people. Usually the entrance fee is always written using Arabic numbers. If you spot the prices written in Thai numbers and Arabic numbers then for sure there are two prices. I think they do it this way because they are ashamed to let you know they are charging you double. I can’t think of any other reason to hide the prices like this.
In the picture at the top of the page, the second and third rows are the prices for adults and children respectively. The last row is the price for foreigners and is clearly written as 160 baht.
Use the chart above to work out the price for Thai people (answers at the bottom of this page). You will see that foreigners have to pay double.
Below are two more examples of how some people disguise the fact they are charging more for foreigners. The example below is different from most as the prices are written out in words.
