As someone who makes use of the automated teller machines frequently, I always notice there is certain uneasiness when clients are queueing to withdraw cash as they keep looking behind their back to see who is standing behind them.
I think there is an easy solution to put the banks’ clients at ease and that is to install rear-view mirrors at the top of the machines where a perfect space is already available. This will allow the clients to monitor who is standing behind them when availing themselves of this service.
