Well, no. 25% to 30% tip for a restaurant meal over $40.
That doesn’t work with a $14 burger meal-deal.
25% of $14 is $3.50
I would never do that to a delivery driver.
$7 or $8 tip. More in bad weather.
I wish that I was Bill Gates’ bastard, love-child.
I’d carry a thick wad of hundred dollar bills for tips. 
Bill Gates has screwed a lot of people.
My mom wasn’t one of them.
