It has some advantages from past experience for visiting the same shop over and over.
You will get a loyalty bonus of sorts after a while.
Benefits ive found is, even if the girl is booked, the shop will move the other guys booking so shes avail for the time you want.
Ive had the odd free massage esp when they are not been busy that day, normally offered around 7-10pm times. Shop fees waived but still need to tip.
On your part It does mean you have to go same shop 2-3 times a week.
