I didn't tip 4 years ago, but, I did offer to pull the cable thru under the house (crawl space) as well as in the attic (temp up there was about 180 degrees that day) -- which he gladly accepted. Plus I already had all holes predrilled. So I saved the guy from getting dirty and sweaty, plus got him out of here in at least half the time it would have taken if he did it all himself.
