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

Let's say you are a 76 year old guy that needs help with a car. You call three guys over and they spend 5 1/2 hours at your place pushing the car into position, hooking up the engine hoist, setting the engine, installing headers and pushing the car back into the garage.
What would be a common and reasonable way to show your appreciation to these three guys?
Keep in mind that the owner of the car is not very mechanically inclined and has to research almost everything.
Lets see some responses. I want to know what others think.
Thanks!
Idk, 3 way with his hot granddaughter..?

Jk.

Idk 50.00 each and beer n food all day ?
Are you friends or just acquaintances?

Beer and food are mandatory for friends, sometimes parts gifts... but it depends on what's going on.
