my friend and i were discussing some of the many things that Boston is missing... 24 hour subway service, 24 hour diners, etc. but the one piece that we thought was missing was the famous rub 'n tug massage parlour. im sure there are a few in boston that we just dont know about. anyone here experienced the happy ending parlour? i for one, have yet to go, but im sure sometime i will make it over to one. What was the experience like? cost? tipping? ettiquette?
