A further reason for a girl to avoid a “long time” overnight session may certainly also be a Thai boyfriend or husband who’s waiting for her at home. the girl staying with you all night, it is surely disappointing if she still insists on “go back bar” or “go back my loom” (sic) after the job is done and your money has changed hands.
Then again, it’s really pointless to start an argument over it.
Better just don’t go see that girl again as she’s obviously not really keen on your company or might even have a boyfriend or another “walking wallet” waiting for her.
On the other hand, if you’ve been rude with your lady, demanded some “non-standard” sexual practices, or argue about paying a price that you’ve previously agreed on, well, you shouldn’t be surprised if the girl wants to leave as soon as the job is done.
You will still have to pay her a kind of compensation fee for extra sexual services or simply for the time she’s investing in you, that’s even if you should only take her out for dinner and not have sex with her, e.g., because you’re too drunk.
This money is usually not paid in advance but handed over to the girl you’ve engaged in a bit of hanky panky in the privacy of your room or when she leaves the next morning.
(We should add though that bar girls in most parts of Pattaya seem to set a starting price of 2,000 Baht these days, or at least give it a try, but will effectively be happy with 1,000 or 1,500 Baht.) In order to avoid an argument with your lady the following morning or just an hour later, you’re advised to always agree on a fixed price for sexual services paying a girl’s bar fine, especially with ladies from Gogo bars where rates are flexible particularly in the upward direction and some girls may ask for 5,000 Baht for “long time” services.
