We have been monitoring DS's money box since December. We were going to bank the contents for him - should have been close to £100, but it was nearer £55, so we've been keeping an eye on it.
We have deliberately not put anything else in since December (and of course never take any out), but today it was down to £35.
In short, someone is stealing from the money box. The only people other access to the house are my mum, and our long standing cleaner.
We only put £1/£2 coins in, so very little room for error with regard to counting the contents.
What would you do? Confront cleaner or just terminate services? For anyone wondering, there's no way this is my mum!
