Didn't really need to ask, it was obvious it wasn't on the cards. There was a male and female, possibly husband and wife. They didn't even use oil for the massage
I also visited recently.
The male, who I saw in reception, was 40'ish.
The female who I saw was nearer 60 so, if there is a family connection, seemed more like his mother than wife.
I agree that it was pretty obvious, from the moment I entered the shop, that there would be nothing more than a Massage available.
However, I thought the massage was quite good. A lot of it was carried out through a sheet.
Chinese massages are more therapeutic (some might say painful) than a more relaxing Swedish massage.
