I have. What is your reasonable excuse for opening a letter that is not addressed to you?
Postal Services Act 2000. It is only an offence if you open someone else’s mail ‘without reasonable excuse’ or if you ‘intend to act to another’s detriment’
It might be something important like a Covid vaccine letter or something time critical. I'd rather someone open my mail and do something about it than put it in the bin.
There was no return address
