IMHO, if you visit a massage shop, and have no pre knowledge of whether 'extras' will be offered, then 'go with the flow'. Most base prices for the massage are quite reasonable, so, in the absence of extra services, you've paid for a massage.
If it was a superb massage, relaxed you, eased out the knots and tangles in your muscles, then score it a positive.
However, if it is known from prior knowledge (or through research on UKP) that extra services are routinely offered, BUT you aren't offered any, then I'd go with the neutral rating.
