So two reasons for my curiosity on whether it was a 60 or 90 massage...
First, during the last year I developed an allergy to a particular massage cream but it took a 90 minute massage to confirm that it was cocoa butter. I was actually breaking out before the end of the session and was able to ask what he was using. Of course the masseur gave me a full refund. Kidding!!
Second, I was wondering if perhaps your stalker signed up for your 90 minute massage perhaps expecting “more” with the longer more expensive session. In your case I wondered explicitly because I saw that your 90 min rate is significantly more than your 60 min rate. Yes, I’m guilty of sometimes inferring the same. And I’ve inferred both correctly and incorrectly!
But no, your situation is pure lunacy and there are zero sympathetic bones to be thrown to this lavender loser.
