Now you know how we pilots feel returning to good ole LHR every trip! Make an appointment of a social nature, then find out the traffic is heavy, we end up being late and missing the one social engagement we have in the week. Furthermore, we then get 'force-drafted' by our management to come back into work the next day, and couldn't have imbibed anyway.
OPn second thoughts, maybe the way to avoid the 'force-drafting' is to book your medical for your return ... be late and miss it .... therefore not able to be forced to work the next day
