Some of you sound like this is a fairly common thing? The porn makes sense, and I think she is doing that for obvious reasons; if you don't want porn on, and prefer music, just say so. This sounds like someone who is concerned about your experience.
For the others, they are completely out to lunch regarding what they are there for and completely lacking even basic customer service skills. If they are agency, make a call and let them know. Whether it goes anywhere, who knows. At the very least, she needs to know it is inappropriate to use the time you have paid for to watch tv while making a half assed effort at providing services.
What's next, she tells you she "prefers" doggy, cuz it gives her a chance to text her friends until you are done? (this actually happened to someone, a visiting sp in AB from Ontario, actually, hmmm) That is not what you are paying for, imo.
And, if you are even put in the position of having to ask her to turn the TV off, already you should be walking away lol.
Actually, until that one I used as an example, I (and many many others) had never heard of such a thing before. Is this an Easten thing (it was a visiting sp in Alberta, actually, lol)
