Based upon that conversation, perhaps there was a miscommunication between lady Felicia & the unnamed suitor over the word RM.
It's just a guess, but what the suitor meant by RM is Relationship Manager - often employed by banks to serve high valued customers to meet its clients daily life needs, from accounting to even recommending best places to patronage & settling the clients financial needs 24/7.
There are many names in regards to such services - such as Chief of Staff to CEOs or Chairman, middle aged or young scion of a family biz empire, as such high caliber top person would need a staff to handle the mundane while they focus on the necessary. Their salaries ranges around S$12,000/mth, sounds lucrative but it is not a job for a family man as it is a 24/7 job, at the beck & call of his boss.....
If that suitor is a high valued foreigner, Relationship Manager is only a term for the more commonly used Butler or Concierge...
Perhaps Lady Felicia presumed RM meant the Malaysian Ringgat$...then it becomes hilariously of NOT who is the Ah Beng, but rather, - my apologies if anyone is offended - WHO is the often colloquially even in western societies dumb blonde stereotypes termed Ah Lian in our cosmopolitan city....
Thus a need for better communications between two to establish a healthy relationship, to know & understand each other's honest needs & expectations better in order for a sustainable companionship relation in the journey of life together...
