Spa’s - so how does it work?

Have never been to Spa before and interested in how it works.

General rules for getting the various services
Fees plus tip?
Etiquette?
Can you request a specific provider? Best to make reservations in advance for specific masseuse?
List/link for various abbreviations?
Red flags when selecting provider?

Thanks in advance?
Read the reviews bud. Look on Reddit. Google will get you abbreviations although I think there's a list on the board if someone knows the link and can provide.

Very short synopsis: 60 or 70 for an hour, 40 for hhr- house fee up front. Get naked, don't cover up. Touch the legs. 60 for handy, 100ish for blowie, 140+ for full service. Some pay more but those prices will get the job done so save your dollars unless you have a special request. You can call ahead and/or request a provider but their English is usually terrible so mostly just don't bother. Red flags- she's ugly/looks diseased?
It’s been fairly simple for me. Only ever failed once to get some kind of extra with 100+ visits to various amps. They pretty much know what you are there for. I tend to do repeat visits with the same providers once I find one that gives a good massage. I appreciate a quality massage. Between that and other fun, always walk out feeling relaxed. There seems to be an uptick in Asian activity in the area. Help keep it that way and don’t post reviews.
1.) most places have entry fees of $70-$100 per hr.
2.) get hundreds from the bank when you pull cash.
3.) walk in and ask for 1 hr. If asked say you were there once before.
4.) when asked for entry fee, open wallet to let provider see the entry fee in $20s and the hundred(s) available for tip (only have what your willing to spend in the wallet.
5.) I lay the tip down in plain sight so there’s no question of what I want.
6.) lay face down on the table and cover your ass with the towel.
7.) when asked, unless you need a massage, say “soft touch”.8.)) as they approach the target area, arch your back and lift your ass.
8.) touch their legs to further the hint, but ask before you touch elsewhere.
9.) enjoy
I would say dont cover your ass, if you must put the sheet on your back. or on the bed I never tip in the open ahead, but everone has their methods
like Bubba said enjoy
