“We trust the fridge” said the oriental-looking stand up guy, Michael McIntyre. Sadly, the comedian’s observation was wrong. Before going away it is sensible to shut down all electrical appliances, excluding the fridge, to prevent, in the worst case scenario, a house fire due to faulty electrics. My friend followed this rule but on his return from holiday he found his fridge had conked out and his kitchen flooded. He didn’t have one of the more modern frost free models. Not only were the goods in his cooler ruined there was also a penetrating pungent smell in the room. Something was off. That’s a shame.
Personally, I’ve not returned from a trip to find a calamity. Not unless you count the number of enveloped bills that have built up behind the door.

Most models are fridge freezers these days impossible to turn off without emptying.
the calamity round here are weeds growing during my absence!
Long live the weeds!
My friend didn’t have an extended warranty, mind you, who does? He had the old thing (fridge/freezer, that is) eight years so it would have been out of date any way. He’s using a small portable fridge to get by with for the moment.
We use house sitters. Not professional ones but friends, too much hassle (and expense) to find kennels for the animals plus I don’t like leaving my property unattended, ever.
When I return my fridge is normally empty!
Christina, we’ve had some lively cheese but never weeds growing in our fridge! 🙂 Our house contents insurance covers such calamaties.
