A question about etiquette ...What to expect for a day of helping people?

He got a super deal.
3 mechanics x 5 1/5 hours x $50 an hour that equals
$ 825.00 labor for 3 bottles of water.

I priced having an engine pulled and a replacement installed the other day on a pickup. They wanted $1500.
Can I get the 3 bottles of water deal. I'll also throw in all the pizza you can eat.

$50 AN HR. / not in Tulsa !! Way more than that . That's why I take care of my ''probly'' best friend when he needs plumbing help, he takes care of me if I rerun into something I`m not sure about , we`ve known each other for over 60 yrs. . Him being an ex 18 time national record holder kinda makes me think he knows his stuff !!
