Cherry bim: you are funny. You are deciding what the people in Europe looked like based on the photo! They posed for their once a year yeshiva photo! we also get dressed up when we take photos. doesnt mean we look like that all the time.
I think the points we can all take out of this, in summary :
1. each person should, on his level, try to make davening more meaningful and respectful. For some it may mean remembering to wear their hat, for others, to BRUSH their hat or shoes. For those who dont wear hats, surely there is a way for them to upgrade their tefillah.
2. Not to judge others. Maybe they have a reason for doing what they do.
3. when you are in shul, concentrate on your own tefillah, not on the next guys
4.Familiarize yourself with the relevant halachos of tefilla and dont take it from the guy on the internet. Not even me.
