I don't mind somebody taking their time to find their wallet, count money or speak to the cashier for a few minutes.
I'm usually not in a rush, and even if I was, watching and learning from this is interesting.
What I hate is the awkwardness and the fact that I'm forced to be a part of it and supposed to be restricted.
If you're going to tell your life's story indirectly to the whole line of people behind you, fine, you probably need it.
A few years ago, I had to wait for my turn at the can recycling machine. This usually annoys me very much, and rightfully so because people seem to forget that someone else is waiting.
But this 60 year old guy was something special. He watched every can before he put it in the machine, as he was thinking "when did i drink this"
I protest against all badly sound-proofed houses. I lived in a house where, if I needed to relieve myself (you probably know what I mean), the lady in the family downstairs quickly noticed and banged on the ceiling.
The daughter in the family had her room right below my toilet, and got angry when I peed, so I ended up doing that in a bottle in my living room and emptied it a few times a day.
It was fight or flight, and I really didn't want any of those. There was a lot of beer drinking and unnecessary damaging of the liver during that year. It tears down your psyche too.
Failure to communicate? As much my fault as theirs? Absolutely, but I don't pay $600/month to basically live with another family, as maladapted as me.
Many house builders should find themselves another job.
