Scammers and cold callers via phone or door knocking.
The door knocking sets my dog off going crazy, most of them are canvassing charities etc, I already give monthly to a few by direct debit, thinking of getting a 'no cold callers' sign for the front door.
Been dipping my toe into online dating recently, 66% seem dodgy....'yeh you're the 1, let's just take this chat to whatsapp (etc) in case of a (insert excuse here) so I can (scam u easier)'.
Edit : another 1 - neighbours who constantly aren't in to collect parcels meaning the delivery driver is regularly asking me to take parcels in. I'm fine doing it now and again but with our next door neighbour it's happening a lot, nowadays we have a good idea of when a parcel will arrive, there's no excuse to be constantly missing them, she's retired she could be in to collect them.
