It's nice to sit in a park and eat lunch. It's less nice to stand in a queue watching other people's sandwiches and coffee being made before you get yours.

This is very easy to avoid: go to lunch at 11:30 or after 1PM.

I think you may have misparsed that sentence. To me, the meaning seemed to be "You'd like to have a nice break for lunch, so you don't want to waste too much of it just on acquiring food."

I’d rather get my shit done so I can go home earlier and spend time with my family.
