Ok, grasshopper listen carefully, you cannot negotiate soapy price with mama or papa sans, the price is already set by the management. Interms of giving tips, usual tips are based on services, if you like the service give her 400 - 500 or if her performance was out of ordinary and you saw stars and lightning give her 1,000! Due to devaluation of US or Singaporean dollars, give her 400. Be generous and return service will be greater and will be grateful!

Don't feel bad you have her 2,000B tip, my friend from Hawaii gave one of the soapy girl 4,000B tip! He's very naive and stupid but a generous guy. Majority of soapy girls are crooks same as gogo girls, so everyone becareful out there!
Good Luck
