There are times when I am at the grocery shopping for our necessities when debit cards don’t work at all. No matter how many times the barcode scanner has read the card, it won’t process the transaction. Glitches like these sometimes make me irate mainly because I rely on the card to pay for my transaction. Aside from me getting irate and all, the head shakes and eye-rolling of the other customers makes me feel ashamed. That’s why I have learned my lesson well, that I should bring cash even if I am going to use my cards to pay for purchases, as simple as that.
