When did the granny realized she was overcharged?
First two times $2 or $3, means she can know she was
overcharged. Then kena again.
Please lah you all. This kind of thing don't never mind
lah. Because it will happen again and again.
If everyone who kena, reports it immediately, action will be
taken early to stop it. The management do not like that kind of
things.
If it happens frequently, there might be a rogue cashier
there. Play your part in getting rid of such cashiers. Kena three
or four times, you have only yourself to blame.
