Privacy issue

Went to the shop to take photo copy of some certificates this evening,

the shop assistant told me that she had difficulties on some coloring pages,

as they were not very nice,

thus I told her to ignore these pages,

at the same time,

I saw her putting the mis-print paper aside,

I immediately alerted her,

for privacy issue,

she should immediately destroy the mis-print documents,

as they were not belonged to her nor the shop,

it is a very common knowledge.

I believe,

in Macau,

many employees in the shops do not pay attention on this thing!
