There are a few embarrassing moments that I could share but I'll go with the time I went to Perth for a conference. I had to get up early to catch the bus to the conference venue and I decided to have breakfast at Macdonalds before catching the bus. Since I am not a morning person I was feeling a bit sleepy. The floor-length windows were so clean that I walked straight into them and knocked my head. Ouch! The worse thing was there was a group of teenagers laughing at me when I found the door and walked in.
