We were at Red Robin and after consuming our tower of yummy onion rings, our Prime Chophouse Burgers, and drinking many glasses of the freckled lemonade, we finally check the bill. It came out to be 28something. He takes out a $20 bill and I take out 2 $5 bills and $3. I put $33 with the bill and gave it to Shaun to check if it was good enough.
Shaun: What is 20+10?
Me: What?
Shaun: ...because I added them separately.. (meaning my money and his money separately)
Shaun: What's 20+10?.... *thinking*.....130!! HAHAHAHAHA oh no wait.. HAHAHAHA 30!
Oh, diyu why do you have to add them "separately" in the first place?
