if you never davened a VERY long Shemone Esrei you have no idea what the poster is talking about
I have, on occasion, davened a very long Shmoneh Esrei. The OP, OTOH, makes it sound like that’s the everyday norm for her. That’s quite different. It should NOT take an hour to daven Shmoneh Esrei every day and the school certainly has no requirement to accommodate her unusual davening habit.
