A lot of the Survey specialists in these missions have been recently recruited out of colonial academia (because the Empire was short of planetary and social scientists) and will have spent most of their lives living on colonies that might be about anything. Other characters (including most of the marines) will have grown up on colonies but been recruited long ago and have spent many years living in Imperial society. And some characters will have grown up in IMperial Direct Jurisdiction or in the Eichberger Foundation ships and habitats that preceded it, and will be entirely used to living in a society where they and everyone they know lives as I will describe below.
The terms and conditions of service with the Empire include free bed and board, free medical care including dental and psychiatric, free bed, board, and education for ones children under eighteen, free use of shared recreational spaces, free structure, free comms and infonet, free air, and "all the uniforms you can wear". There is even a small salary dependent on rank and seniority, plus a pension scheme based on individual contributions. Imperial servants are extremely comfortable and secure: they don't even have to drum up work or worry about business conditions. You don't have to cook or wash up because you dine in refectories. You don't have to do housework because the cleaning robots deal with everything the self-cleaning materials can't handle themselves. You don't have to do much laundry because all the clothes are self-cleaning and wrinkle-proof. You barely even have to shop. And neither does anyone you know.
On the other hand, the quarters are sometimes cramped, and there is little private space to be had. When assigned to a spaceship you might have only a bunk to yourself, and even your private baggage allowance will be straitly limited. The mess or wardroom will be configured as a refectory are scheduled mealtimes and used as a sitting-room at other times. In an orbital habitat more room is available, and private rooms like a college (dormitory) room are usual; most Imperials dine in common refectories, socialise in common recreational spaces, work out in common gyms, and use shared bathrooms rather than paying a charge for a suite with a private bath and maybe parlour. Even in Imperial enclaves planetside, where structure and conditions space are cheap, most Imperials don't bother to take the private apartments that would be affordable under the circumstances. They've being living in barracks for so long that they've learned to like it. Imperial servants only commonly occupy anything like a private home when they are on remote postings and either have a bungalow or live in local-style accommodations. In the IMperial Service you don't have to buy, sell, or find a house.
Imperials rarely own private vehicles. Such things would be stupid in a ship, a futile in even the largest orbital habitat, and redundant in an the arcological Residence in an Imperial enclave. Only in remote postings do they make the slightest sense. Where is it needed, public transport in IDJ is free.
On top of that, Imperial Direct Jurisdiction is a very secure place to live. Everyone living is either an Imperial servant, selected for dedication, self-discipline, and incorruptible honesty, or else a child of Imperial servants being psychologically engineered for the same. There are no thieves, there are no rapists, there are no vandals, and no no-one is significantly violent. Security measures against terrorist attack from outside are thorough and vigorous. And quite a lot of the police are superannuated Imperial Marines doing another thirty years as civvies. These are environments in which it really is true that a lone young woman dressed skimpy party clothes, bedecked in jewels, can tottery in a slightly tipsy fashion from end to end in absolute safety.
There are some joking questions about which the police are even for. There is one theory that they are for arresting Imperial servants suspected of overwork and, if the accused are found guilty, sending them forcibly on furlough.
It is even clean.
