lalag. You seem to be confused.
I have never said that the EU will literally give the UK money (although there is no guarantee it won't come to that).
As has been explained to you twice, I am saying that Leavers assume that post Brexit the EU will compromise their border/expedite medicine deliveries/keep the planes flying because of a mixture of good will and pragmatism; but display complete incomprehension when the EU supports any other country.
It's like listening to children who only want to enforce the rules on who gets control of the car stereo when it's their turn.
You also seem to be a bit confused about the terms agreed around the £850 million:
"As part of this short-term financing package, George Osborne has backed down over the use of the EU’s bailout fund, the European Financial Stabilisation Mechanism, to finance Greece’s short-term needs.
However, the chancellor said there would be an “impregnable ringfence” around the £850m of British money in the fund to prevent any losses to the UK taxpayer.
Speaking after the deal, Osborne said it was a “significant victory and strengthened the protections for the UK in the latest Greek bailout and any future bailouts of eurozone countries”.
He added: “I said British taxpayers’ money would not be on the line in any agreement and that’s precisely what we have achieved.”
In the event of a default by Greece, non-eurozone countries would be compensated using the profits made on holdings of Greek bonds by the ECB"

You should note that the final result was achieved through negotiation, not enforcement, and the UK will always have to negotiate with the EU, whether or not they are a member. The constrictions of international diplomacy and economic reality exist independently of the UK's membership of the EU.
