I’m curious, how do you all feel about punctuality? Does it bother you when people are consistently late, or are you more relaxed about it?

I hate being late.
I often arrive 1 hour earlier, because I wanted to account for possible delays.
Likewise, I feel disrespected, if anyone makes me wait.
If we agree on 10:00, you can expect me to be there @ 9:55 and by 10:05, I'll call you and ask what's up.

Punctuality is important here in Germany. Or at least it was. For me it still is.
