Unhygienic Food Preparation

I eat out most of the time. Be it breakfast or lunch, i patronize the cafes along my way to the office or anyway near the office. There are a few stalls that serve delicious meal...that I like to eat. The problem with these stall is that the cook smoke while they are preparing the dish which turns off my appetite automatically. Don't they know that it is unhygienic to smoke when they are preparing the dish? Why won't they learned and why won't anyone tell them off? I just did that today and by look on that cook's face, today would probably be my last meal there. He look pissed but I know I did the right thing. So all of you out there who encounter the same problem please be brave to voice it out. There are so many illness, diseases these days that we don't need unhygienic cooks to make it worst!
