After initial “wtf” it’s obvious what’s going on. They have to abide by (presumably) laws re track and trace..... but deep down they won’t give a shit. Just give as others have said your punting phone (please don’t say you use your normal or work phone!!), get a burner gmail address if you don’t already have one and anywhere asking for your postcode, well just look up the address of a bank or something.
In the end, they’ve covered their responsibilities.... they’re happy and don’t really care. You’ve covered your arse (except when she’s tickling it) so you’re happy. Everyone is happy.
