In thai culture, sock and underwear are different from other kinds of clothes. Because sock are worn on the feet and underwear is worn on the private of the body, they considered to be dirty, and people who wash clothes for a living often refuse to wash them. However , to foreigers , sock and underwear are pieces of clothing, just like shirts and pants. When they send out their clothes to be washed, they may send socks and underwear at the same time, and expect them to be washed at the same time. Pretend that you have agreed to wash someone's clothes, and he has sent you his socks and underwear together with his shirts and pants. What would you do? Explain or ignore? If you decide that you don't mind washing the socks and underwear,you should at least explain that these are extra, and he must pay more money if he wants you to wash them. Then he might just decide to wash them himself.If he does wash them himself, he may put his socks and underwear to dry in the sun on the same clothesline as the rest of his clothes.Is this the same as the Thai custom? Again, he does this because in Western culture sock and underwear are ordinary articles of clothing
