Seems that she knows its expensive, decides to park there anyway, then complain about it publicly rather than e.g. to the management or someone who can do something about it.

Youre not a 'mangsa kapitalis' if you chose to drive into a high-end mall when there are other options. If youre trying to get internet pity points then youre not in a position to complain when it backfires.

Judging by the high utilisation of its parking spaces, the market doesnt agree with you.
