Chips. Fries are thin pieces of fuck all.
With a jumbo sausage. Self explanatory.
Mushy peas. Peas that are mushy.
And gravy. A sauce made from veggies and/or meats.

I’m so old I can when a pea mix (chips and peas together) went up from 16 pence to 22 pence. I can’t remember why it went up so much though, I was very young at that time.
