How does Martha differ from Mary’s servants in India?

From the text:

The native servants she had been used to in India were not in the least like this. They were obsequious and servile and did not presume to talk to their masters as if they were their equals. They made salaams and called them “protector of the poor” and names of that sort. Indian servants were commanded to do things, not asked. It was not the custom to say “please” and “thank you” and Mary had always slapped her Ayah in the face when she was angry. She wondered a little what this girl would do if one slapped her in the face. She was a round, rosy, good-natured looking creature, but she had a sturdy way which made Mistress Mary wonder if she might not even slap back—if the person who slapped her was only a little girl.
