She has the right to decline access to her home to a stranger fgs!
Who here has said she doesn't, igotnotimeforthis? Seriously, who? Not me.
She also has the right to report it to employer - and as she said she was not malicious in her email.
She's got the right, certainly, and we've got the right to point out that she was being incredibly thoughtless and precious in exercising that right, too. And it doesn't matter if her intent was malicious, if the outcome is that the bloke would lose his job, which all the available evidence points to as a likely outcome.
The fact that amazon trats their employees badly was not known to her at the time of reporting- and even if it was she would still have the right to report!
She's still got the right to report, and we still have the right to tell her that we think her actions are horrible and OTT.
It could have been a poor guy needing a piss but just as easily he could have had other motives.
So what? She didn't let him in. Nobody thinks she should be forced to let him in.
