As others have pointed out - not always possible, and often a bit bizarre. But even discounting that, the fact that one PC is down all his surges and the others are just fine tends to indicate one of a few things:Then why would they? Rest.
1) The PC who is down all his surges is being extremely reckless.
2) The NPCs are targeting a certain player excessively - there may be a good reason for this, but there may not.
3) The other PCs are being extremely conservative.
4) Something funny is happening.
It's also a suboptimal way to do things - if instead of the paladin using 9+ surges, each party member had spent 2 surges apiece (more or less), then they would be ready to continue on for the day instead of stopping after their first fight.
However, my vote is that number 4 is what occurred - the paladin seems to have used an awful lot of surges for a single fight, and is right on the verge of what is possible (and considerably past what makes a good paladin).
