Sorry for your frustrating experience. Try focusing on the good things today brought. Well… I guess that‘s easier said than done, especially for many autistic people.
Punch a pillow, watch your favourite movie/show, sing along to some music, draw/write something or do whatever helps you. Tomorrow is a brand new day and I wish you to have a better one than today!
It sounds as though you certainly have your reasons for being tired and frustrated, an apology is hardly needed for feeling the way that you do - the message is also written in a very clear way.
There is certainly cause to be annoyed in this circumstance, I can certainly see why you might feel cross in response to this behaviour, especially, as you say, when there appears to be a common sense choice.
