I drink a cup of Tea-O every morning from the canteen downstairs if I’m not late for work. A cup of Teo-O costs 25 cents.

If you want to take away, you have a choice of adding a cap to the Styrofoam cup for 5 cents more.

To me, adding 5 cents more for the cap is perfectly ok because it will be 30cents exactly and I won’t have to get back a change of 5 cents. (Don’t we find 5 cents irritating nowadays?)
Until one fine day, when I was having lunch with little boy and loudspeaker, they started commenting on the cap because we packed our lunch and ate at the stone tables outside our office. All of us packed drinks upstairs, but I’m the only one who paid for the cap, whereas they balanced their drinks perfectly in their hands all the way to the table.
Loudspeaker says that he find it ridiculous that a charge of 5 cents more is levied on just a cap.
Me: But the drinks are already cheap enough, even if you add 5 cents more, it’s only just 30 cents!
Little Boy: But why do you want to pay 5 cents more if you can do without the cap? Just make sure you don’t spill your drink on the way to office la!
Me: Mine is hot drink ley, brother. Yours is ribena, spill already also nevermind what.
Loudspeaker: Why will spill? Everyday I also like that hold the cup and bring back office what.
Me: It’s only 5 cents more what, 1 month also spend 1 dollar plus more only.
Loudspeaker: It’s just the thought of having to pay additional cost to something that’s going to be thrown away you know… Me: ok ok.. I will wash the cap and keep it for collection k. From then on, I really kept the cap of every Tea-O that I drank, Now I have five caps.
Actually, the main purpose is to bring the cap with me so that I can cap my drink when I buy it. But it’s so damn embarrassing to do that you know, to cap in front of the auntie when I pay, so I just keep collecting the caps until a colleague asked me: ”what’s the point of keeping the caps if you don’t bring it along with you? You collect so many caps for what?” I refused to do such embarrassing thing. Then a bright idea strike me. Why don’t I find one corner and cap my Tea-O? Then nobody will know that I did such nonsense stuff! Hehehe, ain’t I clever?
