I think it was 1968 when Atkins cafe was opened at Findern on the A38.It was single carriageway then but I never had a problem crossing to the S/W bound lane even in a Reiver or AEC MK3. 
IIRC it opened at 0600 mon-sat and was a revelation in transport cafe design,warm,clean bright and the snap was good.That bloody sh***** down the road called the Airport could have done with some updating to compare with Atkins,talk about a bloody dump 
. The only thing to remember about Atkins was to make sure you paid your parking and not to encroach on the yard foreman’s white lines round the back if you were parking on a dodgy.
