its like the movie pretty woman that got ill treated by walking into a high class fashion store in her normal clothes and then later when the shop owner realised she could afford the stuff the shop owners attitude changes
it actually fun to get off a plane in normal day wear that looks like you belong in economy class and then walk into a tailor to buy a nice suit. their attitude changes in an instant and fun to witness
Someone said to me that it's a trick by the luxury shop employees to buy their egos.
When someone with normal clothes walking into a luxury shop, the employees will not serve them nicely to encourage this person to buy many stuffs or the most expensive stuff in order to impress the employees if he/she afford to buy that.
Well, everyone has their life, but there is a saying that money changes people, and I believe that money can only change some people in some aspects of their lives, but not completely. Some people are wealthy, but they don't act it; even in their mode of dressing, you cannot tell that the person is so rich, and for me, it's cool like that; there's no need to show off when it's not actually necessary.
Because these Old Money already know the life of being wealthy, we as a human being, will search or find something that we don't have or lack of. So they will act like normal people or poor people in order to know how the life in this class and how other people treat them.
