My sister and I had endeavoured to spend a 4-day extended weekend in Lisbon, December of 2012. We were traveling from Grenoble, where it had snowed all day and all night. In spite of the snow, the bus taking us to Lyon International Airport left on time. However 20 minutes into the journey, it took a U-turn and dropped us right back where we started. No explanations were given, the bus driver and conductor brought the bus back to the depot, exited and left all the passengers wondering if they should wait, stay or go! Apparently, they expect us to all process inherent mind reading skills.
