Personal Usage vs Group Usage

How do you define "personal usage"??

Hmmm... For personal use?

Use the items for your personal benefits?

To me.. "personal usage" seems to be in the grey zone of the "group usage"..

If out of your personal benefits, you get everyone to use the items with you, issit "personal usage" or "group usage"? issit "personal benefits" or "group benefits"?

For example, if you know that buying 10 apples is cheaper than buying only 1.. you get 9 other people to buy apples together with you, although you knew that the others don't want to eat apple but dun mind buying it..

Issit personal benefits or group benefits??

Getting everyone to go to the place that YOU want to go is a group activity, whereas others going to places alone is a personal activity..

Using shared item for personal usage got to pay extra while hidden personal agenda usage don't...

pissed with such logic...
