I have often noticed in reading reviews that there seems to be a higher percentage of disappointment among hobbyists booking 30-minutes sessions than 60-minute sessions. Over the years, in talking to both the hobbyists and the Kgirls, this higher level of dissatisfaction seems to stem from opposing expectations and assumptions on the part of both sides.
On the one hand, many hobbyists seem to think they should get all of the services and effort in a 30-minute session that they would get in a 60-minute session, a goal that seems unreasonable on its face merely from the standpoint of the time constraints. One the other hand, Kgirls generally view most guys that book 30-minutes as cheapskates, and so they consciously or subconsciously don't give their best effort. This image is bolstered by the fact that they tell me tips are exceedingly rare on 30-minutes sessions. Just as I think the hobbyists that expect too much in 30 minutes are wrong,. I also think Kgirls that jump to conclusions about guys who book 30 minutes can also be wrong. Because of the unreasonable expectations on the part of the hobbyist and assumption on the part of the kgirl that you are booking 30-minutes because you are cheap, a bad session becomes a self-fulfilling prophecy.
There is an overriding legit reason to book 30 minutes during the week. Many guys I know book hour appointments on Saturday and Sunday, but will book 30 minutes on weekdays because they are leaving their work, often during their lunch hour, to try to get a session in. However, the guys I know are not trying to sample a girl's whole menu in 30 minutes. Its usually a quick shower rinse, sometimes solo to save time, then BBBJ and mish or doggy to completion in the bedroom. They will usually skip the DFK and DATY, so the session is basically about them getting off, and not too much effort for the girl. These guys have also booked hour sessions on the weekends with the same girls, where there is more time to do more things, so the girls come to understand its not about these guys being cheap, its about them getting some extra time with their favorite girls but only have half-hour spurts (no pun intended) in which to do it. Many will still tip on the 30-minutes session.
The Kgirls' negative view of 30-minutes sessions is not from these guys, but rather the ones that want them to do everything non-stop at an exhausting pace just so they can save $50-80. I've read dozens of reviews where guys booked a half hour and then slammed the girl with a low score because there were "5 minutes left and she refused to start round 2." This behavior just screams "cheap-ass" and this happens more than the other type of hobbyist in the previous paragraph and therefore shapes the overall negative view of 30-minute sessions on the part of Kgirls in general. Just ask a Kgirl what she thinks about guys that book 30-minutes, and at the very least, you will get an eye-roll. Others will start swearing in Korean. Some will launch into the difference I have stated here, that some guys are okay, but that many are jerks.
Personally, I think the solution to get good service during a 30-minute session is to book a one-hour session the first time you see the girl. At the end, tell her you would like to see her a lot more often but you can't always get away for an hour plus the driving time on days you are working, so you could only see her for 30-minutes some times, but are reluctant to do that because you don't want her to think you're cheap. Since you have just booked an hour, she knows you have the capability to do an hour, but circumstances may not always allow it, so it conveys the impression that its not a money issue, but a time issue. Most are understanding, and will put you into the first group of two paragraphs above, and not the second group, who are the more obvious cheapskates.
