Re: wearing masks
According to the official Government guidance, the following groups are not required to wear a face-covering while using public transport, in a shop, pub or restaurant:
A child under the age of 11
People who cannot put on, wear or remove a face covering because of a physical or mental illness or impairment, or disability
An employee of the transport operator, or in any other indoor setting where appropriate when they are acting in the course of their employment
Where a mask causes the wearer severe distress
An emergency responder such as a police officer, paramedic or fire officer acting in the course of their duty
Someone speaking to or helping anyone who relies on lip reading, clear sound or facial expressions to communicate
Someone acting to avoid harm or injury, or the risk of harm or injury, to themselves or others - including if it would negatively impact on your ability to exercise or participate in a strenuous activity
While some people have genuine medical reasons these exemptions have and will continue to be exploited.
