I work for a multinational, in computing. A few years back, when I was responsible for IT services in our European HO in Brussels, supporting a number of high-flyers, guess what was the single most frequent cause for laptops being rendered inoperable:

Spillage of wine, whiskey, gin and tonic etc, all over the keyboard.

How come?

Easy - just think of hundreds of busy execs, squeezed into their seats aboard an aeroplane, trying to balance a laptop and a drink on that little table...

As for cellphones and liquids: My wife must have some kind of record. Dropped two different ones in the loo (dead), and once, having it hanging from a strap round her neck while disembarking from a boat in shallow waters, she dropped a camera into the watre. Immediate reaction was to retrieve the camera from the water and - you guessed it - into the water goes the cellphone too, as she bends down...

These things are sent to try us.
