Most people confirm that it is much cheaper to make a drawing, a "matacho", a work of art, write a note or write down a phone number, whatever it is on a ticket than buy a white sheet to do it.
The cost of a drawing sheet comes out relatively in a quarter of a day of work so people choose to scratch our bills and then see if they are discarded when they buy or simply throw them away
Incredible but true...
