As a (formerly) truly self-employed person if I promised to attend at
a client's site all day, it wasn't expected that I could just take a
break whenever it suited me.

But didn't you get paid for the whole day, meaning that all your time
during that working day had been paid-for?

I've never specified how many hours a day, but typically I'd do about
13hrs a day, albeit to include commuting time if required. Normally the
client pays for any overnight accommodation.
