When I was 18 I got told I looked 14.

When I was 18 and flying back to school, the lady at immigration asked 'is there someone waiting outside for y- *sees my birth year* oh never mind you're alright.'

When I was 21 and didn't specify what ticket I wanted on the bus (adult or child), I got given the child ticket (which was 15 and under) 25% of the time.

When I was 26 I was asked the first and only time in my life by an air hostess 'would you like wine with your meal' (I flew semi-often for school/ visiting family). It hasn't happened since.

When I tell people I'm 29 they go 'huh really? wow we really couldn't tell'.

When I told a friend that I'm turning 30 they said 'can you still get the child discount in Disneyland if you asked?'

And while I do look different to when I was 16, 18, 22 etc, as John Mulaney said, "I don't look older I just look worse".

tl;dr - no one respects a 5'4 29 year old.
