Many sports clubs, institutions or companies have access to a canteen. The law is strict and requires smokers to smoke in a separate room. Moreover, the non-smoker must not be bothered by the tobacco smoke from the smoking room. Sending sporting members, employees or visitors outside is not an option because of a bad image. You want to keep employees close to the workplace to keep productivity as high as possible, in the case of a sports canteen you want to keep the turnover going by keeping the customer inside.
