Gatsby had dismissed every servant in his house a week ago and replaced them with half a dozen others
Gatsby fires all his servants because he is afraid they will gossip about him and Daisy. He doesn’t seem to care who he has hired to be his servants, as long as none of them went into West Egg Village. In truth, his previous servants might have been a little more loyal to him.
The implication here, supported by later when we find out they’re Wolfshiem’s people, is that these so-called “servants” are actually crooks who needed a cushy gig.
