This is what happen:
me : Hello welcome to switch!
Customer : Hello, do you all sell Pen?
me : Erm......... sorry sir, but we don't sell pen. If you need pen you can go to popular is just behind there (I pointed at the popular shop)
Customer : No No! I'm looking for the "Apple Pen"!
me : (Stunt for at least 5 second! Looking at him with full of heart to talk to the customer, mouth open! but voiceless!!)
Customer : My friend told me here have.
me : (Still voiceless! but i start to understand what he mean in a wild guess! "Stylus"!)
*Stylus is a stick as the pointer of most of the touch screen phone.
me : Sir, you mean stylus? the stick that can use to point things at your touch screen phone?
Customer : (with a Happy face) Yes Yes!!
me : Sorry sir, our shop don't sell stylus.
Customer : How come? you all apple shop mah, how come no apple pen for the phone 1?
me : You mean for iPhone? iPhone comes with a multi touch screen, using finger touch noneed stylus.
Customer : That's why! my finger so big! the touch screen keyboard so small, how to sms?? and my friend told me you all sell.
me : No we don't.
