I'm as working class as they come
My eldest dc went to a school where one mum showed up to pick hers up after being down at weatherspoons and having a pint or two for lunch
The school rang the police because she was pissed and ss got involved
We moved to a very middle class area and my younger dc went to the middle class school
Mums would go for lunch at a posh restaurant and had a couple of glasses of wine,rock up to pick up dc and nobody batted an eye at how pissed they where (I'm talking slurring and falling over)
Working class school-the kids would be immaculate with smart uniform and smart haircuts
Middle class-2nd hand,scruffy uniform with long (add points for slightly greasy and matted) hair and dirty fingernails
The working class parents would have the newer,posher cars
Middle class-cars that looked like they would never start again and normally covered in dog hair
