Answer:
Among the complaints about the Enlishmen that the author´s grandmother is:
- The habit of not taking a bath twice a day.
- That they ate in front of each other.
Step-by-step explanation:
Ethnocentrism is when people disagree with the culture of other countries, so they have prejudices against people who come from that country. Usually, ethnocentrism is a faithful defense of one's own culture without taking into account what others think; for these people, there are only their values.
For example, we can see that the author's grandmother does not agree that Englishman do not bathe twice a day, and just thinking that they can not bathe is inconceivable to her. All this is because she has other values, customs, and criteria different from the Englishmen but can not accept that it is good to have differences, and this is a clear example of ethnocentrism.
