[SE] Sanitized Metabolism: how useful is +1 in in 'close confines', like 'elevators'?

[vicky_molokh]

Greetings, all!

Sanitised Metabolism grants '+1 to reaction rolls
in close confines (cramped spaceships, submarines, eleva-
tors, etc.)'.
Now, I'm wondering just how often the opportunity to benefit from it actually arises. Now it looks like a significant part of the time, it would be deliberately arranged:
Sure, either you're on a submarine/spaceship, or not. But making sure the make the important requests when you 'accidentally' end up riding the same elevator as your target seems like a viable strategy.
It also seems that at least half the time, it's easy to arrange a close approach when using Sex Appeal: as long as it's possible to get close to the target, either the +1 helps get a success at Sex Appeal (so you end up being a daring but very-well-reacted-to character), or it fails, and you get a Bad Reaction anyway (so you creep out the target one way or another, and it's extremely unlikely to make a difference).

Thoughts on the topic? More viable cases of application?
Thanks in advance!
