Two things:-

Thing the 1st:-
When Ah waz a lad ... We all took our hats/caps off indoors, unless of course we were either doing the Flag bit on Church Parade in Scouts or of the female persuasion.
Thing the 2nd:-

Just spotted the ubiquitous dumbphone, causing total removal from the fact there was A.N. Other across the table.

The "Extra" caught my eye @ Surgery.
