Robert, from East Kilbride, was in the bar with his partner Mary when the helicopter struck.
The 61-year-old's daughters Claire and Elaine accompanied Mary on a visit to the site of the crash yesterday.
Speaking from East Kilbride, Mr Jenkins' long-time friend Isabel Douglas, 79, who was a good friend of his late wife Margaret, said: "Robert was a real gentleman.
"You don't get many men like that any more.
"I saw him on Thursday and he was dressed so nicely and well turned out."
An emotional Mrs Douglas pointed up to the sky and added: "I feel like he's up there now with Margaret."
Mr Jenkins' next door neighbour Tracey McGarva, 37, said: "He was so kind and would help out whenever he could."
John McGarrigle's tragic death has left a grey cloud hanging over his home town of Cumbernauld.
The 57-year-old - beloved in Glasgow's poetry circles - was killed in the Clutha helicopter crash as he enjoyed a Friday night drink.
He was a regular at the bar, as well as the nearby Scotia, where he often attended poetry recitals.
Mum-of one Dionne Chivas remembers 33-year-old Colin Gibson, from Ayr, as a cheerful person who was always smiling.
She said: "Colin was my cousin's partner.
"He was a lovely guy who would speak to everybody and he was really family orientated. He loved to be around them.
"It is just so sad that he passed away. He will be sadly missed.
"I never had a dull moment with him. You were always laughing and smiling in his presence."
