In the wake of the recent robbery at Standard Chartered Bank ("Suspect on the run after $30k bank robbery in Holland Village"; July 8), which did not have a security guard on-site, many people have called for having security guards in every bank branch.

But in many branches, we find security guards doing other duties, such as welcoming customers, guiding them to take a queue number, helping to fill up forms, and so on.

This should be avoided in the interest of the security of the bank. What if a robber comes with a partner who distracts the security guard with his other duties? This is a recipe for disaster.

Security guards should focus only on their core duty of security. Banks should not use them to fill their shortage of staff.
