Personally I think this case macam recycled cans.

You habis minum you campak, tak recycle and jual kat recycling centre.
Tapi bila orang kutip nak buat duit recyling tetiba you hangin.

Just halalkan je TS. Anggap sedekah atau amal jariah. Dapat jugak pahala.

just sharing a story here:

>last month went shopping at tesco with my dad.
>didnt bring tesco card
>cashier asked if can use her card
>dad said yes
>she swipe card, and becos purchase a lot, got cash voucher (not much, RM2 only i think)
>she give the cash voucher to my dad
>my dad says it's ok, she can keep it for herself
>she hesitated, but my dad insists
>she said thanks, and gave the brightest smile that made my day

i wish i can make everyone smile like that, but at the same time i myself ngam2 cukup makan..
