My first tip in pagtitipid: Know the signs!
When someone says the following lines…
(1) Tito, pasalubong ko? Gusto ko ng….
(2) Birthday ko na! Regaluhan mo naman ako ng …
(3) Orlee, nasa mall ka? / Pupunta ka sa mall? Uwian mo naman ako ng….
…Before they could even finish their sentences, immediately pick up your “ringing” phone and tell him / her, “Ay! Wait lang. May tumatawag,” then slowly walk away putting the phone on your ear.
If the one who said one of the introductory lines is already the person on the phone, tell him/her, “Hello!? Hello!! Choppy ka. Ha? Ay! Di ko marinig,” then drop the call.
