General question as per title:

From my own personal experience getting a FS from a ML ($200+ for 30m) is more expensive than going for an escort ($150+ for 30m), but I see many punters prefer to go with the ML for full service and was wondering why that might be?

a few random thoughts:
Escorts have comfortable beds vs an massage table.
a bit more privacy vs 4 other blokes being in the adjacent cubicles.
You can choose an escort with a body-type that you like etc. vs. luck of the draw etc.

Curious to know your thoughts.
