Luck Hari, the most underrated reoccurring character?

Despite seeing one Cafe Nervosa waitress regularly in the first half of the series and knowing it was the same woman, I had never been aware of the name until today: Luck Hari played the same waitress regularly during the first five seasons, to the point where she showed up more than quite a few reoccurring characters!

To put into perspective: by the end of the series, she appeared in more episodes than Ronee, Sherry, Julia, Simon, Frederick, Lana, and Sherry, was tied with Bebe and Mel, and even Lilith only had her beat by a single episode!  As well, Gertrude was only in 18, and Noel only doubled Hari at 22!

I'm surprised that the writers didn't do more with the Cafe Nervosa staff, considering how often the Cranes visited!

I can recall that actress. She appeared in some memorable moments and gave some funny lines from time   

When Frasier changed his order so man times but still asked how his coffee was going in My Coffee With Niles, she replied with "Oh, we have a team of specialists working on your coffee".
