#1. Being given a 9:15 am appointment time for kidney/bladder ultra sound requiring consumption of a litre of fluid an hour before and THEN finding the actual time is 9:30 am so they can get the paperwork done before the procedure starts - and then them not being on time

Geez I hate that.
#2 Traffic lights on right turn slip lanes leading to freeway on ramps. Guarantees a traffic bank up on the access ramp and some timid clot at the front can't merge properly with the result that you get people riding your bumper. Geez I hate that. ( I haven't seen this kind of problem in Europe, but there the access points are arranged as roundabouts and the on ramps are NOT close together.)
Not so funny story: A few years back we were on tour in France and the coach stopped at a "Tolled" motorway service centre for a break. Back on the coach after a klick or two the couple behind revealed that one of them forgot to pick up the handbag - and inside it was her passport issued by the PRC and also with it the "green" card that allowed her to work in the USA. Phone call reveals that the bag is in safekeeping back at the service centre. But to get it involved a twenty klick ride to an off ramp, a forty klick ride back along the motor way to the nearest off ramp beyond the service centre and then another 20 klick ride to the service centre. Geez the Tour Director hated that and so did the coach driver - talk about schedules getting shot to ribbons. The TD later confided that a "lost" passport was the only reason that a coach would go backtracking.
P.S. I get to have the ultrasound tomorrow

You work it out.
Cheers
