Here's a weird food ordering

When he goes out to get fast food, he NEVER comes back with he right stuff.  Then he gets pissed..SUPER pissed.  He tries to blame the people working there, but it always seems like he is really blaming himself.  I never seem to have the same issue. 

Recently, I was with him in the car and I didn't understand at first what he was ordering, he was saying it all wacky and I could see how the people inside would be confused.  Because I am learning to speak his language, I could see what he was doing though.'s SUCH a no big deal for me to order fast food and with him, it's a crazy complicated thing that gets screwed up and becomes a source of frustration and shame.  And I just wanted the damned chicken sandwich without sauce!
