Don its pretty much the same scenario as when you are listening to music in your car.....get home shut off the car at tonight ....next morning get in the car start it up and the music is blasting......BUT last night it was fine......it's all how your ears adjust to the volume....just like the couple in from of you at the table ... after a few songs your ears adjust and mentally they think you lowered it for them as when they first walk in it seemed loud .....same thing with air condition when you come in from a hot outside environment into a colder room....very annoying but a professional knows how to handle the situation.
