Sweet tea town?

I was in New Orleans a while back, and while eating at Cafe Masperso I tried to order sweet tea, and was told by the waitress that New Orleans was not a sweet tea town. Well I have never heard this. I have made many trips to New Orleans and have always ordered sweet tea. I know that New Orleans is different than a lot of places in the south, but this statement just sort of caught me off guard. If any of you know any info about this please share.
I hope to be posting more in the future. I know that my posts are not regular, but hopefully I will begin to have a daily post.
