I rest my case.
I do a LOT of Dead Head at first class, and I have seen delay up to 55 minutes were crew had to get more fuel for different reasons.
( Remote de-ice. Slott change after startup. Updated flightplan with new winds or reroute with 200kg more fuel required.)
This summer with minimum Plog fuel is a good plan for a diversion.
Or pushing my luck, and I do not rely on luck.
As the SAS Purser said to the new Fueler in CPH when asked": Cpt, how much fuel do You want , Sir?"
" Well ; Son ,topp Her up"
The Cpt and Fo showed up ca 30 min later and was told by the Cabin Capt they were all good to go.
2 hrs later they pushed after some DE- fueling to max landing weight on the 2 hr sector.
Turns out the 737 takes ca 24 000kg of jet A1.
Off setting some crab pots!
You All Have a Good Day.
