In Germany and most of Europe there is no social stigma associated with going to these places. So what if you run into a client or boss at these places? They will just think you're one of the guys who likes to have a good time. Only in the US will you have problems (although you wonder, if 2 people are in a place like this, then why think poorly of the other guy when you too are in it!!). Places like these cannot exist in the US because despite what we like to believe about being the most liberated country in the world, we are most certainly not. Too much damn social insecurity...too much trying to decide what is wrong and right.
