Ditto. If the other guy absolutely hates the idea of having the same stats as the rest of the party, give him 25 points, not 28. There. You rolled for him, and you didn't roll quite as well. Problem solved.
For a one-shot, mind you, I'd have no problem. But for a long-term campaign, it just irks me profoundly to end up with an average character standing next to gods who rolled better than I did One Time. If most of the "I wanna roll people" really wanted to roll and let fate pick the results, there wouldn't be a rules (and usually additional house rules) allowing rerolls or "best character of five you roll" or whatever.
