You've got people who are housebound, aged, ill, lack-time or otherwise unable to get about, so is online shopping all that bad?
As for the check-out operators... they are increasingly being replaced with self-serve registers, now if only they would work properly, and serve us the way they are meant to.

I do most of my gift shopping for interstate relatives online because it's cheaper than purchasing the gift from a face-to-face store then sending it in the form of a registered parcel in a separate transaction.
And I am guilty of having purchased bottle water from an airport vending machine on numerous occasions because it's often cheaper than purchasing it from an airport cafe/store or on the plane.
You guys are going to hate this then...

If you were starving, would you contemplate a vending machine pizza?
Or fancy a cup of hot chips perhaps?
A western Australian enterprenure is rolling hot-chip machines out across Australia by the end of this year.
