Due to modern gadgets available in most of the households it is not difficult to prepare a few items in short time for such guests. In fact in every house there are some items already available in the kitchen which can be heated and offered to them. Sometimes in emergency a large proportion of readymade condiments is also admissible.
The guests also are a bit concerned about their odd hour knocks on the doors and will be accommodative to that extent.
So in todays world it is not a big issue at all
