Making change
Over on the Freakonomics blog, they interviewed Scott Adams of Dilbert fame. One of the Q&As jumped out at me:
Q: My all-time favorite Dilbert cartoon is the one where he gives some kooky well-thought-out amount of payment for an item so he’ll get back an even dime, and says it’s for the clerk’s convenience. Do you really do that in real life?
A: I don’t do that. I prefer to use my mind for daydreaming while the cashier works out the math.
I do that all the time. I’ll buy something which costs $6.26 and have a $10 bill but no 5, so I’ll pay $11.26 instead to get an even $5 back. Or if I don’t have a quarter but I have three dimes and a penny, I’ll pay $11.31 and get $5.05 back. I’d never thought of that as being particularly weird, but in thinking about it now, maybe it is. Hmph.
