Your friend does all his writing using:
He is constantly rewording sentences and editing his writing.
He is also quite new to editing with this software.
You should really send him a command cheatsheet, so he can stop abusing his keyboard and, more importantly, his flexor tendons.
I started by researching futhark, Germanic/Teutonic, Anglo-saxon runes. I don't interpret the characters too tightly as "modern" letters. (Note: These are stylised characters, bull past the flair to "see" them.)
The crosses ARE Greek as suggested by a few commentators in the article linked to in OP. I don't see how the crossbars at the tips ...
The cookbook should have read: "Reduce the recipe temperature by 36°F." (Or perhaps 35 or 40, for a "round" amount—"36" implies an unwarranted degree of precision.)
The original source that the cookbook was based on presumably said "reduce by 20°C." However, Celsius and Fahrenheit are relative scales (with different definitions of zero), not absolute scales....
Instead of inventing ice cream (which will definitely change the molecular make up of the milk, by the way), you could also venture deeper into the lateral thinking loophole abyss and
Mission accomplished. Because loopholes.
I believe that the answer is
To expand a bit on that, let's consider the 3 possible strategies (considering only the filling time and waiting time):
Refill my bottle first, then try to take the bus
Try to take the bus, then refill my bottle later
Refill some first, try to take the bus, then refill again later

@MatthewJensen has provided a very reasonable possible explanation. The OP has however indicated that the car left the parking spot before the rain. This prompts the consideration of an alternative mechanism:
In fact, if we constrain ourselves to inside-the-box thinking in a car-in-the-rain situation and approach this as a physics problem, these two ...
This puzzle is called a "Baguenaudier" which is French for "Time Waster".
This solution assumes that you are holding the handle end on the left. The rings are numbered from right to left starting at 1.
The solution to the puzzle involves a couple possible moves.
1) The first ring is always available to put on or take off of the bar. You take it off the ...
