Don't pay more than $35-40. You should get a massage for that, good, bad or indifferent will depend on the attendant. So will happy ending, if available, but usually some assurance of a tip beyond the door fee will be required. No horrible consequences are likely, if you ask whether upgrades like topless, nude or the 'you touch' NR, and BS are available at extra cost. But you well may get a "No".
If the door isn't opened when you knock, you might have done better by phoning ahead, but if they didn't post the number on their sign, how could you? And who's to say they run on time anyway. Come back in fifteen.
Make up your mind if you want FS, and if that's the case, you should be in one of the two Escorts forums. In the Massge Forum, FS is an accidental extra at best, and mostly disapproved.
For a guaranteed good time, read the reviews, and resolve to visit a place many have reported favourable details about, rather than picking a place by location, and hoping for the best. That MO is only for those who value exploration ahead of outcome.
You can do a Search on "Bloor" in this forum and see what folks have reported instead of asking for them served on a platter.
