I should think so

[Francois]

My understanding is that it means 'definitely', with some impatience -- as though the answer were obvious. Am I correct ?

Cambridge dicts come out with the following sentence:
"I bought her some flowers to say thank you." "I should think so too."
I see no impatience here, just approbation. So there are several uses, right ?

Could you provide some examples, with different tones if possible ?

We use this some in the US. There is impatience there. It conveys the sense of "it's about time you thought of that" :wink:

I think the timing would show whether there is any impatience or not- it doesn't sound impatient to me.

Hmmm. At least in AE, the non-impatient form would drop the "should", but we don't use it as much as you Brits. :wink:
