Benmore Botanical Gardens

Sitting outside the cafe, man, mid 50s, louche looking with Chelsea boots, leather jacket, jeans and a cigar. With him, a woman wearing a black hat and long black trench coat. She is reading to him from an IPad.
We return to cafe 90mins later. She is still reading to him. Occasionally he chuckles appreciatively. Mainly he stares into middle distance, continually relighting and dragging on cigar.
Who are they, why are they doing this?
My guess was aging member of half famous band. G went for author having his latest work read back to him. Any other ideas?
