Shisha bar: ventilation and CO warning are not a side issue
Operating a shisha bar produces carbon monoxide from the glowing coal. The responsible authorities therefore regularly require an adequately sized ventilation system, CO warning devices and documented maintenance. Several states have tightened enforcement in this area; business closures for shortcomings are not uncommon.
On top of this comes state non-smoking protection law, which only permits the business under certain conditions, and tobacco tax law for the shisha tobacco used. Anyone taking over an existing bar should review ventilation logs, maintenance records and the latest inspection reports from the regulatory authority before discussing price.
