These last few months almost everything has had the same smell on it. Whether it’s letters through the post, items bought in the supermarket, anything at all. It’s a very distinctive perfume smell. Doesn’t matter where it was bought or who delivered it, everything smells like this now.
My guess: someone was shipping a huge quantity of something scented, and it wasn’t packed securely, and it broke open and got all over all the sorting equipment and now everything that touches that machine smells like that now.
I’ve seen similar things happen.
The only thing is this is happening from multiple different delivery companies and supermarkets that use their own couriers.
