maid tying lace

there was a video posted on the free video/photo sharing site, STOMP. the video showed a maid obviously being mistreated, tying her owners lace.
but why did the maid do such a thing, which is obviously an embarrassment to herself. maybe of the very fear of losing her job, and being sent back, was probably enough to weigh out the staring eyes of the public.
although she is a maid, she is not a slave. her owner has only paid for her services, and given her accommodation, but she has not bought the freedom of the maid. yet she uses the power of money and employment to control the maid. she is obviously abusing her authority.
yet others actually sympathise with the plight of the now notorious woman, noticing her limp she had in one of her feet. yes, maids make life easier, but not so easy till the extent that she cannot even take a seat to tie it herself.
but the people going up the elevator were also too much. although they noticed this act, they did not do anything or say anything to stand up to that act, maybe they thought it was OK, or just because that woman was a maid, so they did not care less.
maybe, just maybe, the maid used a limping trick so not to be seen as evil.
i fully agree with the person who videoed it, STOMPer 'Larvitar', when he said, this is obviously abusing her authority, others should have common sense, maids are not slaves, they are helpers.
