went to the lounge at 5th lev few times, the PRCs need the guest to accompany them up there, they were stoppedf by the security if they go up themselves.
Basically, the PRC just help to serve you drinks and chit chat with you, at the end of the day you just tip them a bit will do, normally we just tip them Rm10~20 per night, we did ask abt the FJ but sadly all turn down politely by them. May be we are not handsome !
hope this help?
