He kena scolded for not having $50 change , or he angry at paxes for using $50 to pay for taxi fare ?
Taxi drivers must have $50 change , if still shortage , must try to find atm titi some loose change one .
If just coincidence ran out of $10 , explain to pax and show them your amount of those $50 notes .
Say if can , can u drive her to the nearest ATM ?
Or pay by NETS ?
Or pay by visa , u can even absorb the 10% service charge ? But 7% GST must pay lar .
Many options .
Scolding pax is never an option .
