I've never managed to get into the habit of always carrying my mobile phone around. I'm always
forgetting it or leaving it somewhere so it's not unusual or suspicious if I don't answer the phone.
The wife just thinks ... stupid old Jake forgot his phone again.  

The soap smell can be a real problem - women have very sensitive noses. But, encouraged by the
wife who's a great believer in the power of massage [we often go together], I'm in the habit of
taking regular health-type massages with no hanky-panky involved. So if I've visited a WG, I just
tell the wife I've been for a health-massage. No problem.  

Sounds like you've got it made

Sounds like the voice of experience.  

Yes, but wouldn't your wife get suspicious when you tell his this every day ?  or am I assuming
your sex drive is too high ?      

Jake, I can't help thinking your mobile phone habits are premeditated.

Re the "soap" smell ....   Roger_that, does your hotel have a swimming pool?  Just pre check your swimmers into the pool locker and hit the pool as soon as you return to the hotel. A nice touch would be to call Mrs "Roger_that" from the pool deck after you are wet, and ask if she wants to meet you there for a swim and a drink?

TwiceAweek says you may be doing too much planning, but maybe that's part of the buzz .... planning and execution of the perfect mongering crime right under the nose of the inhouse constabulary.

He is right though in one aspect, you say you don't have much time so you do need to spring into action at the first opportunity for a quick hit and run. Keep in mind for 141 walk-ups you will likely spend a lot of time going from door to door, floor to floor, before you find one of your preselected chickens on-site and available. It can be quite frustrating, especially with the clock counting down, and other Bros will be hunting too .....

Yes this idea was made into a HK film by a local Hong Kong film director call Pang Ho Cheung and it even had a sequal.  It achieved reasonable box office success in 2003 but the sequel was a complete flop.  The film is called:

Men Suddenly in Black
http://en.wikipedia.org/wiki/Men_Suddenly_in_Black (大丈夫）

Synopsis:
After their wifes are going to Thailand with her friends, Tin and his friends Cheung, Chao and Paul decide to grab this golden opportunity and enjoy 14 hours of freedom by putting their work aside and betraying their spouse.
