Sometimes, if put ourselves in their shoes... everyday, they
have to face demanding and impolite Singaporeans who might
disrespect their profession and be rude to them and all that.
They're poorly paid, and there might be just one of them when the
sheer volume of their job might actually necessitate another staff
or so.
Not making excuses for bad service... but sometimes, we have to be
a tad empathetic and a little less ready to 'see your manager /
supervisor' and lodge complaints against service staff.
