Yes, this is true. Even in the Terma Like Centaurus. There is a Gringo rate upon entry. They essentially make gringos pay for the session upfront where the other termas will charge you after you session. And you are not forced to session.
Same in BA Argentina - At Modelos; the locals told me that they did not have to pay a cover. Also, every girl in the place was negotiable. The hobbyists on ISG said an SP should do FS GFE for X amount fo Dollars but she will try to charge X+Y so don't go for it.
So there are plenty of situation where you had better bargain.
Montreal is different. The agencies on MERB quote a price and it is the real price. So know the rate and pay that rate. I have always found that bargains are not really bargains. You can find this on BackPage but it is a crap shoot. If a girl advertizes too low a price, a reg flag should go up.
I have bargained once for a girl that was sitting in the car all night. this was when I had to spend a night in Montreal due to a layover on my way back from France. Her reviews were so-so for looks and every time I called this agency that night she was always available. A definite B-lister. I offered to do her for a slight discount (it was late_) The booker accepted and she came over and rocked my world.
All the other discounts I ever had were due to promos offered by the agency or discounts they offered because they were late or something like this.
Rule 1: Know the going rate for the market you are hobbying in
Rule 2: Pay the rate
