If a punter books an SP in the belief her "professionally edited" photos will be materially representative of how she'll look in the flesh then they're a fool.
How a punter behaves influences how an SP reacts so as much as OP has the advantage of broadcasting an encounter where Paloma is at fault, her reaction at the door is equally believable if he behaved in a less than amiable way in her perceptions, e.g. his face visibly fell when he clocked her and didn't like what he saw. Given her spunky responses here, it's possible her "aggressive" instruction to get in the bedroom could've been a misinterpreted playfully curt "get in the bedroom then we're running late" to try to move things along (and see if she could win him over if she cared to or empty his wallet anyway).
Turning on your heels because you don't like the look of an SP is par for the hobby.
If you're "promised" a young, lithe, happy superhunny sex kitten and you get a 40+ dumpy wreaking of fag ash in a housecoat and stained slippers then by all means cry foul. In the case where you were advertised a young, attractive, English woman with a sparky attitude and you were welcomed by a young, attractive, lippy English woman there's not a lot you can determine beyond that unless you follow through with the booking.
Inferring a poor performance because you were disappointed and had done nothing to spark a positive reaction from the SP is you projecting your own unvocalised criteria for the sexual gratification you wanted to buy.
Paloma's public AW "pro" pics are in line with most "reputable" 150ph London agency girls; glossy pics that belie an attractive but "less perfect" (more real) body in person with ZERO promise of the personality you actually meet. If you actually bother to read into her advert then there is obviously a sassy personality behind it, but whether that's her or not you could not be guaranteed.
No idea if any of the other real photos (not the splodge ones) were present at the time the booking was made but hopefully she'll leave all of them as a more honest impression of the looks more naive punters will be expected to cope with!
