Today at Borders in Singapore, when paying for an origami book.

Cashier: “Do you have a Borders membership card?”
Me: “No, but can I have a 10% discount anyway?”
“No” and after a few seconds in a hush voice “Ok, I’ll give it to you anyway”
“Thanks”

A few moments later I noticed a package of chewing gum on the cashier’s desk

“Isn’t chewing gum banned in Singapore?”
“Yes, but I use it anyway. Want some?”
“Yeah, sure”

Communication is good.
