What is the proper islamic way to speak to woman/customers at work. When speaking to them, can we look at them just for this need and then look away. In the UK, it is considered rude if you speak to them whilst lowering your gaze completely. Can you look just for the need. They make even complain.

Ustadh AbdulAziz al-Haqqan

Lower your gaze as Allah commanded you as much as you can.
