Excellent guru. Definitely worth a shot.
Jan made comments that we felt were racist towards brown skins. He told the group that Prague has a lot of Indians doing the odd jobs such as dishwashing. He knew we are Indians, we told him that in the introduction; he still had audacity to make those comments in the group. Common, man, we're tourists helping you and your country pay bills, show some respect. Even if you have some personal buttlers at home, don't say that out loud, it could offend a larger group. However, I can quote 5 such incidents in Prague in a matter of a day where people were profiling me for my skin colour. Risking of making the same mistake of generalization myself, I think racism towards brown skinned people is common in Prague (I remember Vir Das's tweet too). I will never visit Prague again. Greate history in Prague. But all useless if you can't respect and include everyone.
Just didn't enjoy. JR should make it more interesting or find something else. I averaged out the opinion of 5 others (met later after the walk) in the group, just to make sure that I am not the outlier, before I leave a review.
