Print resume

Go and print out resume at the shop nearby my home.
Black and white(B&W) - RM0.60
Colour - RM1.20

Yeah, expensive, but the time and petrol to travel to a cheaper shop make me willing to spend it.

Converted my docx into B&W pdf format and ask her to print it out.

Tadaa... it seems that pdf somehow still retain the colour data or the printer screw up. Anyway, they end up in colours. Uh huh..

I ask her, "So?"
She hesitates, "I charge you as B&W price, 3 pages for RM1.80. Don't tell other people"
And she kind of cover the papers and hand it to me.
Face benefit?
