I have no trouble imagining that since the spigot is already connected and sits in a cabinet (visible on the photo), you can't peek inside and it won't occur to you to poke it. Unknown unknown.
I also hate cleaning my spigot for that reason - there just isn't enough wiggle room in the cabinet to put it back leak-free after I unscrew it.
Good point. If he wasn't around when the sink was installed or at that point never knew that the spigot was important, there's be no reason to have noticed the block.
