Have to agree with you, queuing for most of the times, is the
least productive unless as a last resort. It's like waiting for biz
(passive) instead of looking for biz (proactive)! Was OMO for 6+
yrs, 8 am to 8 pm.
Put on yr thinking cap....
Where and what are the likely activities that will take place
during these hours? e.g:
going to and coming back from lunch, hospital
visits/appointments, meetings;
tourists going where and when;
some work second shift, knowing the likely places to get them is
from sweeping experience.
Also, if CDG, any incoming calls just whack! This is opportunity
beckoning.
