237SJ - you don't say whether your accomodation was a basic B & B, or a single-owned hotel, or a chain hotel.
From a chain hotel, if i gave them notice I was leaving early, I think offering a continental breakfast would be reasonable, and I would ask for it, and be unhappy if i did not get it, and write to the manager to complain.
If it was a family hotel, or a B & B, I would think it unreasonable to expect that as a facility, but reasonable if you gave them at least a day's notice in advance.
