I think I've figured it out. Worst Bus in Edinburgh have clearly identified the number 86 service between the capital city and Dalkeith as losing money hand over fist. This will be why this morning, when I left the house to get the 7.40 bus to the city centre there was a large queue of disgruntled passengers at the bus stop. At 7.45 a bus arrived. Unfortunately this was the 7.33 express service - although I use the term loosely - which only stops at certain points. The 7.40 was not far behind, presumably once the driver had finished the crossword in the Metro newspaper.
But I can see Worst Bus' ploy. With buses either alarmingly late or just not turning up at all, with drivers who know Krakow well but are clueless when it comes to darkest Dalkeith, and with a timetable that may well be on the shortlist for this year's Booker Prize for best piece of fiction, Worst will feel if they can drive enough passengers on to Lothian Buses they can withdraw the number 86 altogether.
And they can use the money saved on not providing buses for some other persecuted part of the Lothians...
