Dior Galerie w/o a reservation - 2 hour wait even if starting the line before opening?

I’m mistrusting of this information said to me by the worker. She told me there would be a two hour wait, I said something along the lines of “Aw ok, I guess I’ll just come tomorrow and wait a little before it opens”. She said something along the lines of the line being a two hour wait regardless of the time of days. She then told the people right after me there was a one hour wait for the no reservation line, lol
