I have no issue in seeing a male receptionist at a MP. Same experience at JR and Suko (sometimes Jack and Joe) and with the male owner at Ellagance.
I talked to a MP owner (who actually fired the old dude) and she agrees that a male receptionist will not turn customers away. Another good thing - the girls will feel safer if a male receptionist is in the shop at late night. To me, I feel awkward to ask a female receptionist about the service level of the girls.
Honestly, I felt uncomfortable in seeing the the old dude at JR for the first time a few years ago. I then have no problem in meeting him at E&M, IU and EB. This old dude, though looks creepy, provides the best customer service and a well mannered telephone conversation among all other guys I met at the front desk of other MPs.
