1 Monty: How did your cousin get into the hotel business, Sallah?
2 Sallah: He started at the bottom and worked his way up.
3 Monty: Ah, good old determination and honest hard work.
4 Sallah: Yes. Every time someone more senior died he took their identity and job, until eventually the owner died and my cousin just took over the whole hotel.

The only way this could be any more "good old determination and honest hard work" is if Sallah's cousin was murdering the people whose positions he was usurping...
