A Question of Loyalty

[Hakon]

I think that there must have been some Orc captains who thought they could steal the ring and become the new dark lord.

'What d'you say? - if we get a chance, you and me'll slip off and set up somewhere on our own with a few trusty lads, somewhere where there's good loot nice and handy, and no big bosses.'
'Ah!', said Shagrat. 'Like old times.'

Also that quote has one line that bothers me. Like old times. Why would the Orcs call that old times? It is almost like they are talking about a time before they were Sauron's servants.
