You know why? Because all the chefs I know say the same thing - smoking is the only way to get any sort of break while in the kitchen, going outside and standing still doing nothing for 5 minutes is not acceptable, but somehow going out and smoking for 5 minutes is absolutely ok in most kitchens. I know some people who picked up smoking only to have an extra break at work.

On the plus side, I also know someone who bought himself an e-cig and somehow buys "blank"(saline/water filled) cartridges for it, just so he can have a short break but without any side effects of actually smoking.
