OT: Tipping contractor for driveway refurbishment?

[Stavs]

If you're that ecstatic with the job, I would see no harm in gift certs to a restaurant. I did that for my deck guy. Whats an extra $100 on top $9-10k. He also went way above and beyond what his base estimate was for free. Its up to you and what your gut says.
