Thailand's tourism service industry is worth mentioning. The Royal Wharf Hou Ship District offers free tea, coffee biscuits, seasickness medicine and six kinds of ground coffee. Free drinks, mineral water, watermelon and pineapple are provided on board, free buffet lunch is provided on the island, every bathroom is very clean, and every yacht is equipped with a snorkeling deepwater pier, which is so rich and perfect. It's just 340 RMB per person for a day's tour, which is worth a lot of money. It's just real socialism. The boat owners are friendly and diligent, and they serve well. There's no slaughter at all. Tipping is also voluntary. When they come back to sea, the service staff at the dock handed out a wet towel to each guest, which is very considerate. It's a worry-free consumption.
