Does this bother anyone else?

I feel like it's unrealistic that the characters just go about in public and are never mobbed by the public. Every once in a while it's described that they're recognized by people, but in real life they definitely wouldn't be able to just walk around in public. I mean just think of ANY celebrity. Then add in them being attractive mysterious billionaires. There's no way they'd just be walking around Prague in crowded tourist locations without causing an absolute riot.
