Read the following excerpt from a US court opinion:
```
the costs of an expert witness, that it is the service of the subpoena on the witness, not the service of the subpoena on the opposing party, which is dis-positive. Town of Chapel Hill v. Fox, 120 N.C. App. 630, 632, 463 S.E.2d 421, 422 (1995). Plaintiffs concede that subpoenas were served on both expert witnesses for which defendants sought costs. In sum, we find no abuse of discretion in the trial court’s award of either deposition costs or of expert witness costs. Accordingly, the trial court’s order awarding costs to defendants is affirmed. AFFIRMED. Judge TYSON concurs. Judge JACKSON concurs in the result by separate opinion. 1 . We acknowledge that this Court’s opinions have been inconsistent with regard to deposition costs. Compare Oakes, 173 N.C. App. at 520, 620 S.E.2d at 48 , with Morgan, 173 N.C. App. at 581, 619 S.E.2d
