Yes i clock watch but i don'tmake it obvious, When I go to an appointment it's clear to me that time management is needed, My hairdresser starts with my hair and 30 min in offer me a drink and then another client to start on because time is money, Same for anything else be it a chiropractor or dentist but not Doctors they are always running late lol Thing is most guy's I see want to feel special and running over makes them feel special so I have to have plenty of time between bookings.
I have a cd that's just an hour and I know when it ends it's close to time over but I get regulars always staying 15 min over so I then have to plan my next booking around them.
