happy minus

i learned just today that you cannot use a combination of load balance from your happyplus card and cash to pay for purchases.  (ok, maybe it's in the FAQs but, uhm, i didn't read...  :"} )

my happyplus purse and points balance was short by P10 for what i was buying so i gave the cashier my card plus P15 cash.  (error on my part, should have been just P10.  i'm a math genius, wahehe...)

she told me minimum load is P100.

i said i was using my load and just adding the difference.

that was when she told me about the oil and water nature of load and cash:  load and points you can combine but cash and load, no.

so P10 and i have to load P100?!

aw, happyplus...  why???  : }
