She probably doesn't pay attention at all because she doesn't actually care.
Most of Monica's work/notable roles was when she was working for ADV Films. Her best voice work is probably Hyatt from Excel Saga. If you actually listen to it she sounds nowhere as obnoxious as she does today.
During this same time, she was a frequent guest at anime cons around the country along side people like Vic. It's obvious she got a huge ego during that time because look where it lead her to now.
EDIT:
After a little research I managed to find this video. Around 23:20 Greg brings up an interesting fact about anime companies and conventions, he also claims that Vic called him, Chris Patton & Monica Rial "The Trifecta" because they were always at cons back in the day. It's definitely worth a watch if you can put up with Greg Ayres talking for an hour.
