I was this funny incident in OP today. The Mandarin speaking Malay sales girl was talking to a customer, a guy in his 50s.
Customer: The Nikon 70-200 how much har?
OP: Three zero five zero
Customer: No, no, I am talking about the 70-200.
OP: Ya, three zero five zero
Customer: *In shock, cannot parse*
OP: Three thousand and fifty dollars.
Customer: Can't be. So expensive?
OP: 70-200 Nikon right? Three thousand and fifty dollars.
Customer: *silence, in disbelieve*
The customer must be thinking he stepped into a "black shop"
