I didn't encounter a bad crew member the whole weekend. I made a point of going to the info desk when I left on Sunday to thank the crew there and let them know I'd had a great time and that everyone had been helpful, and to thank them for their time - I figured far more people would go there to complain about something, and I wanted to pass on thanks for my good experiences.
I thought the blonde woman managing the queue in photo area A on Sunday was very good (I didn't catch her name) - I arrived for an Eve Myles photo and the area was running behind, but she kept everyone informed as to what was happening, kept the queue area organised, and continually had a smile and was in a good mood. It could have been so easy in that situation to be grumpy or let the area fall into chaos, but she did a fantastic job at keeping it orderly and the wait happy, not tedious - which of course meant even though things were running late and I was worried about getting to my next shoot, I didn't get disgruntled, and the people around me all seemed in good spirits too even though we had to wait longer than we thought we would. So definitely a massive congrats to her for being so positive and good at what she was doing!
