If we say £24,000 per month is based on her hourly wage. The average month has 30 days which is £800 per day.
The average working day is 8 hours. That's £100 an hour! She's also a lazy cow so wouldn't put that much effort in. So, let's say, feasibly for wear and tear, she does four hours per day that's £200 per hour.
She isn't worth 50p an hour. The state of it and all of the BaCTeRia
Edit: I did further maths. £24k per month across a year. Got the average weekly earning and then using an average working to calculate her hourly earning as £147.70!
Let's round up to £148 per hour. All I can say if any man is paying that, God help that ugly fucker.
