Pizza

At pizza shop in the late night:

   me: Could I have one slice of pizza?
   shopkeeper: Only one slice?
   me: ???
   me: Ok. Two slices. (That's fine. It is just one more dollar.)
   shopkeeper: Why not three?
   me: 0_o
   me: (Oh!. He gonna hit me T-T)
   shopkeeper: Three?
   me: Only Two. (Please, don't hit me. T-T)
   shopkeeper: I will give you another one for free. Choose one.
   me: Ok. This one. (feel relieved)
   shopkeeper: I will give you another one. Two free slices. Is it Ok?
   me: o_O => O_o => => O_O => -_-

Finally, I got four slices of pizza at midnight.  It is so unhealthy though.
