Thank you David, but I am afraid your recollection is flawed! The expression you are looking for is ‘ chip butties’ The word ‘butty’ or ‘butties’ is a northern (North England) expression meaning ‘sandwich’
The word ‘bottie(s)’ is either:
1. A child’s term for ‘bottom’
2. Perhaps more disturbing… The word to describe the desirable traits of a burlesque performer (Chicago slang)
Have to admit they were good – when we got them that is… about an hour and ten 
minutes after we ordered!
I remember you enlightening me in our flat in 1977 Paul on how to make ‘chip botties’ (I think the tt in botties is silent)
