These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Scrappy Mechanic: One of the conditions to become a 4 Star hotel is to have a VIP park in the parking garage and stay in a Suite and be satisfied. The only way to keep your hotel rooms from being infested with cockroaches is to put in a hotel service room so the maids can clean it. You cannot remove service rooms once they are placed. You could just as easily use that space to put in something much more useful and financially productive, but then the only way you can give the VIP a good chance to stay in a hotel suite is to build a ton of them, let them be used, destroy them, and put them back in. Very expensive, all because there is one type of room that cannot be destroyed.
Combining these facts leads one to the seemingly sensible conclusion that your limited supply of elevators are better served being devoted to residents. There's no reason you can't just build a Housekeeping unit on each and every floor that needs one. If there's no reason for service workers to move between floors, they don't need service elevators.
