Question on etiquette for massage parlors

I'm new to using massage parlors and need some advice. What is the proper way to ask for extra services? Come right out and ask or wait until the provider brings it up? Also, what is the a typical "tip" above the house charge to pay for these services? Will the tip vary depending on the length of the session or the particular service. For example, if I want a 90 minute massage rather than 60 minutes, I know the house charge will be higher. What about the tip for additional services?
I'm in Rochester if the city makes a difference in the answer.
Thanks in advance!

Plenty on info in the reviews posted but having PA will help giving you far more info.
If you're only there for extras, just book 30 mins. If you really enjoy the massage too, then do an hour. Some girls are terrible at massages, some are great. You just won't know until you know. She'll start to tickle your yam bag, and you'll know it's on. Then she'll probably just ask you what you want. Just tell her. It's much less complicated than you think. Go somewhere that it'll be a sure thing. Check for reviews.
