Maybe 2-5mins, if they had to sort something out first with a person in front of me
Usually I go in, have a line of 2-3 people at most, and just tell my name and address, go vote and I'm usually done in like 5mins altogether - 10-15mins for the process is already something I've never experienced and would pretty much get to my nerves...

Yeah, I'm already very happy with my setup
Even my wife can use it with apps and so on
So, the only thing was the language stuff.
If that really fixes it, I'm more than satisfied :-)
