Now I kinda know why my mom used to say this. I truly never thought of her house as a hotel, but maybe she had the feeling that people thought it was.
It's really unfair and circuituous because you can't explain about being in service (should I add an adverb with a modifier here?) and nobody (especially children & dogs) will admit that they think they live in a hotel (except for the people that do, but who does anymore?).
And another thing. If it were a hotel, wouldn't the laundry be whiter, the floors cleaner, the meals gourmeter and the bedding higher count? And certainly the proprietrix less broody (if only to herself).
