English: The Khlong Saen Saep Express Boat service operates on the Khlong Saen Saep in Bangkok, providing fast, inexpensive transportation through the city's traffic-congested commercial districts. The service has a checkered reputation, due to the polluted water in the khlong and the haphazard nature in which the service is operated. The 18-kilometre route is served by 100 boats of 40-50 seats, and operates 5:30am to 8:30pm daily. Prices are 8 to 20 baht, depending on distance travelled. The service carries about 60,000 passengers per day. It is run by a company called Family Transport. Source: en.wikipedia.org

Pratunam is a shopping district in Bangkok. It is a major market area with thousands of fashion stores that sell wholesale with cheap prices guaranteed, especially if you buy in bulk. Pratunam is used in a broad sense here, and it also includes the areas of Victory Monument, Ratchathewi and Makkasan.

The southern boundary of Pratunam is marked by the Saen Saep Canal. This canal was dug during the reign of King Rama III in the mid-nineteenth century to connect the Chao Phraya River with the Bang Pakong River to the east. When Saen Saep was connected with Maha Nak Canal and Krung Kasem Canal, a gate was required to control the water level between them. Pratunam means "water gate". It was not developed until the 1960s when rice fields dominated the landscape. Around that time, a fresh produce market was set up near the Indra Hotel at Ratchaprarop Road. Since then more markets have set up here, and the whole area has become known as a local marketplace. Source: wikitravel.org
