Indonesian to English Art/Literary Poetry & Literature early 20th C. Indonesian novel in Malay lingua franca

A long-time trusted employee of a Central Java sugar mill is retiring. The mill offers to buy all his property, including fields, oxen, carts, buildings etc because it is all essential to the mill's operations. A committee inspects and values everything and makes him a fair offer, which he accepts. However, the mill owner -- a nasty Dutch woman -- is angry that he's been paid so much and calls him a 'geladag'. Sample sentences in which the word is used include the mill owner's accusation, "Saya pikir dia sudah mencuri dari pabrik, itu geladag!" and the administrator's reply, "Saya berani katakan, mandor Joyo jauh dari pantaran geladag, jauh dari perbuatan mencuri atau menipu."

I think 'geladag' means someone who is money-grubbing, who seeks to get more than he deserves, who outsmarts and bilks others. What do you think?
