You go lunch, buy a can of drink and finish up your lunch. Walk to machine, find long queue or 2 auntie/uncle with 4 bags. You wait or bring back?
Wait. So need to factor in machine return time and also can only eat around places with machine.
Go back office with dirty can. Wash in toilet and keep at office. So bring back home or bring to machine the next day?
Bring back home. So along the way home, decide to detour to machine. Done.
But 1 day out of 1 month, no time to detour, coz want to party with friend, how to bring 1 empty along.
So keep at office. Next day, go eat same places near machine and return. Bring an empty can and buy a can of drink, 2 cans, 20 cents. Woohoo.
Colleagues say dont go same place eat lah, so may end up with 3 empty cans in office. Finally going to places with machine, bring a bag of cans and take back money.
OR, once a day, make going to machine a part of daily life. sometime vist the machine 2 or 3 times a day depending how many meals are taken outside.
Headline: Singaporeans are the greenest people in the world #1 that they can make a trip to the recycling machine daily. Sometime even up to 3 times.
