I've worked up a bit of a thirst after all that walking

[zoobinshid]

Hello everyone,
Would you please tell me the meaning of the sentences in parenthesis in this short conversation?

A:(( I've worked up a bit of a thirst after all that walking )) and this looks like a really nice pub. Shall we go in ?
B:Why not ? (( We could do with a rest.))

Thanks in advance,

[Tdol]

It's just a way of suggesting that a drink is justified.

Thanks tdol,now what about ( we could do with a rest )

[mykwyner]

Both of these expressions (and thousands more) mean, "Let's consume some alcohol."

In this context, "we could do with a rest" is just a further justification for stopping at the pub for a drink.

In other conversations, people will say this when they are tired and want to take a break from whatever activity they are doing. The "we" includes the other people involved in the activity, partners and/or opponents, and so makes the idea more acceptable to the whole group.

I agree with y'all. We could do with a break (form what we are doing right now). :)

The sun's over the yard- let's get a drink in.
