United Airlines 737 MAX 9 IAD to AUS UA381 N37510 (Weather Delay)

The 2nd leg of return trip from New York. We had some weather south of Dulle airport which held us up for 45 minutes before we could takeoff. While we waited on the taxiway the flight attendants served us water and we were even allowed to use the facilities if we had to. I was in the bathroom when the pilots said we were #3 for departure so I had to rush back to my seat so we could takeoff. This was my first time on a MAX 9 but this one had no IFE screens.
