When I saw ETOPS and liquid vulnerability in the same thread I was going to ask, as a passenger, whether this would be a problem. Wrecking a computer by spilling a drink is one thing (though many laptops are designed to be at least spill resistant), stopping an engine is another. And although I am sure pilots are trained against this, it's still a highly predictable event.
