Left a pint of milk in the fridge, a packet of biscuits, some individually wrapped tea bags and all the keys, instruction manuals etc.
Received a box of manuals, the parish magazine, a list of useful numbers (cleaner, gardener etc, none of whom we can afford) and a card with a welcome message. They took the mechanism that opened the garage door and an extra 5k thanks to some shifty dealing so a bottle of wine would have been nice.
Appreciated the clean house and loo rolls though, esp as the previous house we got left an unflushed turd in the downstairs loo and a bunch of junk in the loft and behind the shed.
