I don't pretend to know what goes on in the background. Maybe it's disrespect, maybe it's miscommunication/lack of knowledge, I don't know why she wasn't acknowledged. She had a visible spot in the merchandise section, however, so it wasn't like she was hidden in some dark corner that nobody walked by.
I stopped by her booth and honestly I was shocked that she was doing EVERYTHING. Taking the order, walking back to get the merchandise, opening the package, signing the shirts/posters, collecting the cash. Maybe it was just when I was there, and she had help at other times but man...that was rough to watch. I was going to get a poster for my office but the line was too long and I simply forgot to head back there.
