Smoking laws have changed and been updated over the years to put an unjust burden on business owners. If you are opening up a business you more than anyone needs to be aware of the different laws including those involving smoking.
Almost all restaurants are not able to allow smokers inside today and instead anyone who wants to have a smoke must go outside before they light up. This is much different than just a few years ago when you could walk into almost any store or business and you were allowed to smoke. The main reason they cite for this change is second hand smoke. If you are picky and want to eat in a restaurant that does allow smoking, you will have to do some research and find out which locations still offer this because there are few.
You can hardly even find bars that allow smoking these days. It is so important if you are planning to start up a business where you are going to be serving customers that you find out whether or not you can allow smoking. There are certain establishments such as casinos which are often able to permit smoking inside. They usually need special permits for this though and in a lot of cases it will cause the business to go down because there are more aggressive non-smokers pushing for smoking bans than there are smokers standing up for their rights.
Think about who your target audience is and whether they would prefer a smoking or non-smoking environment. It really all depends on what your customers want as to what you should be offering them. With bars and casinos on the other hand you know that it is the older age group you are working with and most of them will be smoking anyway. A lot of people like to smoke when they drink and gamble so you may bring in more business if you allow smoking.
Especially if you are just starting up a business make sure you take the time to learn details such as these. This is something that could make or break your business. It also means you will have taken the time to decide what is going to be most suitable for your customers. The smoking laws will probably continue to change in the future as well so you will want to keep an eye out for this.
