whom she bought.

She told the salesman that you have… cheated me. I cannot transfer file from my previous laptop..
Salesman : Madam, can you please try infront of me.
This is what She did,

1) Right clicked the mouse on the file which she wanted to transfer and selected CUT option.
2) Disconnected the mouse from that PC.
3) Took that mouse carefully and connected it to the other PC where she wanted to copy that file.
4) Right clicked the mouse and selected the PASTE option.

Salesman fainted….
