A couple of years ago I received a mysterious parcel from M&S.
Addressed to me, no message, it contained a faux potted plant.
I asked around the usual suspects, but no-one claimed to have sent it.
The kicker was that the pot was broken, in 3 pieces, but welded to the faux soil.
I took it to the local M&S food ... to askwould they please tell me who had sent it, and would they replace it due to damage.
The answer was NO in both cases.
Date protection laws were quoted, and the manager had no discretion to replace.
I came away with not so much as a box of chocs .. and the broken pot still sits on the windowsill in the downstairs loo, in case the giver ever comes to call !
