Dio mio / Duw, Duw, where DID you find that?? 
That’s exactly the shop and the family. I was born 200 yards away from the shop on Beaufort hill nearly 74 years ago. I used to spend half my summers with my Beaufort grandparents in my birthplace and visits to “Jake’s” were a regular treat - usually for icecream (between wafers rather than a cone) and occasionally for chips.
Jake’s son’s accent in this marvellous film is authentic Ebbw Vale. Abergavenny (12 miles down “Black Rock”) is a bit posher. Ebbw Vale (or Glyn Ebwy as it bacomes during Eisteddfods) has its own sing-song, idiosyncratic dialect, which is very dear to me. An example would be “I do go down b’there often” for “I often go there.” “By here” meaning “here” is pronounced exactly like the French pronounce “Bayeux” of tapestry fame.
If you (Gisella) remind me when we meet in Tregaron, I’ll be happy to talk to you in fluent Beaufort (and maybe a bit of Welsh, too. 
)
Diolch o galon / grazie tanto for this wondeful, nostalgic link.
