Feel free to complain until you’re blue in the face, chump

Back in the Twenty-First Century, “complete” vacation packages would leave out things like drinks and meals. That $999 tour of Europe ended up costing several thousand dollars when you factored in those items, despite their appearing on all the brochures.
These days, vacationers are still ignorant of what’s missing in these kind of heavily discounted tour packages.
Sure, you can assume that gravity may not be present if you’re in a spinless hull. But woe be to the traveler who goes to sleep in their cabin and misses the alarm signalling the end of the complimentary ten minutes of oxygen.
