We're more interested in more time off, rather than more money.
Not what they want according to your earlier post
Then our wants aren't the same and to be honest, I'm not bothered about what they want; but I infer, from the fact that the boss says he prefers the guys with families (as opposed to the single blokes who just do the minimum) that there's some scope for deciding how much and how long you wish to work for.
I mean I didn't want to look like a slacker, so I didn't ask those questions outright.

My plan would be to get my feet under the table, make a good impression, and then start slacking. That attitude served me well in my first 17 years of employment, so I don't see why it wouldn't continue to work.
