American culture that should not be imported into Korea

(1)The pizza is 15 dollars, the tip is 5 dollars, and the tax
(2)I spent $23 on pizza. This isn’t it, America
(3)The tip that I used to give 10 to 20 is basic 20
(4)I used the drive-thru
(5)What kind of service did they do to me? What on earth
(6)And even if I give you a tip, the company will eat it all
(7)Please, we need to improve this culture
(8)I don’t want to spend $20 a day as a tip
(9)I’m telling you. I’m not rich
