How would you react in this scenario?

[Loveel]

You come home from work/being out.

17year old has been cooking and left the kitchen in a right state. Think dirty plates/cups/bowls all on the worktops not put in the dishwasher.

Airfryer used and left dirty, used dirty pans left on the hob, baking dish left full of half eaten pasta bake.

Teen has gone out and left it like that. This is a regular occurrence despite being warned not to leave the kitchen like that.

What do you do?

I would

Not clean anything
Change the router password.
Stop funding the teen's phone/pocket money/giving them lifts
Collect all the dirty stuff and put it on their bed

Tell them to clean the kitchen when they got back. Once the kitchen is clean I would give them the router password. With the understanding that I'll change it again the next time they leave a mess.

Once the kitchen was consistently clean after they used it for a few weeks I'd start funding them again
