There are various opinions about whether to claim a previous visit or fess up to a first time. I generally tell the truth.
I think the repeated questioning is a feeble attempt at screening.
It doesn't sound as though anything could have ameliorated your session, though. Even (or especially) if they suspected you were LE, they should have given you at least a quality time on the table with a good legit massage.
The MMS here has explained to me that she's fighting a vicious circle. When there are bad reviews, business goes down; when business goes down, the quality of the providers who will sign on goes down; when the quality of the providers who will sign on goes down, bad reviews are written, etc.
