Fascinating.Well a lot of the places I work if you don't work around the phone signal it is easy to get stuck which is inefficient. Dore and Totley and Liverpool South Parkway (the latter even have pre printed cards for when the TVM fails) were the usual two problem stations pre COVID. From Dore I used to do my usual grip and take note of references then stop Hathersage to Earles Sidings and around Chinley to print TOD recalls and hand them out in Disley Tunnel, making use of the dead signal spaces to check/hand out TOD recalls and good signal spaces to sell/print.
From South Parkway unless they were making local journeys I used to batch print after Warrington and hand them out before Manchester.
Working out little things like that keeps your brain working in what can be a repetitive job.
I didn't realise your route knowledge also included knowing the varying strengths of the phone signal.
