As the manager of ABC Bank you have recently received a number of complaints
from your customers about the way they have been treated. Some of them have
not been served for more than half an hour. Most of the complaints took place
during lunch hour which is ABC Bank’s peak time for business. This has been
brought to your boss, Mr Ahmed, the general manager’s attention.

REQUIRED:
You are told to write a memo to all the sales staff instructing them how they
should deal with visitors and customers who visit the Bank. They should take
shifts for lunch and maintain at least a certain number of staff at all times. They
should also come to work on time and any tardiness will be subject to
disciplinary action. They also need to clean up their own area of work before
they leave work for the day.
