People not wearing masks on public transport

Neeta from Mount Albert

In this pandemic situation, rules are meant to be followed, for your own safety, and if you are considerate, for others as well. Is it that hard to have some kind of face covering while travelling?
On the bus I took home this afternoon- there was a group of 4-5 passengers chatting away loudly, NONE of them had any face coverings on. Every other passenger and the driver had it on. I just got annoyed and moved to a different seat.
Level 2.5 restrictions include mandatory face coverings on public transport, but who will monitor people who flout the rules?
AT staff are unable to do this- so is it up to the passengers to handle the situation, or just get off and take another bus perhaps? What is the immediate practical solution, before we hit a setback on the number of cases?
I might try and contact AT and see what they say, not expecting a prompt response though!
