The question is "Everything included in price?" Say it to mamasan right after she quotes the base rate. In Bangkok most erotic massage places quote low for massage only, then girl demands extra for handjob, more for prostate or oral. Asking "everything included?" forces mamasan to clarify what happy ending covers. If she says no, negotiate full package upfront or walk. Works every time in Sukhumvit and Silom shops.

Best question: "No extra tip okay?" Ask the girl directly after choosing her, before going upstairs. Bangkok erotic massage girls often accept base price then slow down or stop if you refuse big tip. Saying this sets expectation. If she hesitates or says "up to you", choose another girl. Saved me hundreds of times in Nana and Phrom Phong parlors.

Ask mamasan "Full service happy ending included?" using those exact words. Vague "special" means different things. In Bangkok some places include handjob only, others prostate, few include blowjob. Being specific forces clear answer. If she says yes to full service happy ending, tip stays reasonable. My go to line at every Asoke and Thonglor erotic massage spot.

The killer question is "Can finish strong no problem?" Ask the girl privately before undressing. Tests if she will rush, ruin, or demand extra near the end. Good Bangkok erotic massage girls say yes confidently. Bad ones look away or say "maybe". Switch girl immediately if unsure. Prevents edging hell and weak endings in Sukhumvit oil shops.

Ask "Girl drink tea money how much?" before paying anything. Many Bangkok erotic massage parlors hide the real cost in "tea money" demanded at end. Mamasan quotes 1500-2000 baht, girl wants 1000-3000 extra called tea money. Asking upfront reveals total cost. If too high walk out. Essential for every happy ending booking around Terminal 21 area.
