Embarrassing story! You know you want to laugh at my humiliation! :-P

Okay, so we were at Gare d'Austerlitz waiting for our train to Barcelona and I had to use the bathroom pretty badly. I asked probably 5 people where the restrooms are in the train station. I still couldn't find it until a security guard stopped me and said he was watching me go round and round the station and that I should have asked for help. He basically walked me to the bathroom. I forgot you have to pay a bit to use public bathrooms so I walked back to my parents in shame. I ended up waiting until we boarded and used the restrooms there for free.
