Don't like the Skin

I saw this old lady on the train in fornt of me eating apple. Now theres nothign wrong with that. But then after each bite she spat the peel into a clear plastic bag.

Chomp, munch munch munch, spit
Chomp, munch munch munch, spit

She didnt seem to avoid the peel either. Purposly eating and spitting. Im not sure of where the practice comes form but I only spit if in dire need. But everywhere I look in Sydney I'm surrounded by people spitting. on the trains, waiting of the bus.

Not onto grass or in a bin but pretty much evetywhere. I guess it's the equivilent of dropping your cigerette but where ever you please. What do you say to someone that has just hocked a piece of snot next to you? pick it up? Rub his/her nose into it.
