I'm a cleaner and understand people's houses are going to be a certain level of messy/dirty else they wouldn't need a cleaner but some are just vile!
One family went away for 2 weeks and their fridge was left with opened milk, very very out of date food in the fridge, bins all over flowing. I wasn't going in until they'd been away for over a week so its not like they thought it would only be there for a day or 2 until I went in. I don't do their fridge normally and it was only that I had bought them fresh milk for coming home that I saw it all and got rid of a whole binbag of stuff.
Another family have gone away. Been gone a week. I went in yesterday and the smell knocked me sick.... They'd not flushed either of their 2 toilets after using them so it's been left stewing. There was meat in the fridge and again opened milk. There was spilt cereal that's had milk on it all over the settee. I get that people have busy lives but there is just no need for certain things to be left! Their kids never pick up after themselves including food wrappers/yoghurt pots and this standard of living just seems to be becoming the norm 🤢
