Girls at Tiger for example will do both and you save $20 opting out of full service. Usually from what I’ve heard that’ll include everything except intercourse so bj’s, kissing and daty.
DATY is sometimes extra. Ivy for example asks 20 to get her peach juiced orally. Kissing also not usually to be expected- maybe some LFK at most. YMMV.
You already know this, Wcr, but for the less experienced going half-service to save 20 is usually not worth it IME. Pay the girl full rate and the options remain less restricted, and her attitude and service will be superior. Just common sense. Calculating menu items a la carte vs FS rates that are typically all inclusive can lead to confusion and misunderstanding.
Sometimes better to just ask- "So, FS? Kissing, bj, daty, titfucking, body slide, fucking, digits, COT, COB etc.....?" Anal, rimming, CIM, COF are usually not to be expected without upcharge (Although young Dina happily indulged my facial and CIM requests! Stephanie too.)
But for me, I just go with the flow and guide the session, letting it evolve towards a very interactive experience without resorting to any formatted checklist or menu.
Whatever works.
