After thinking about the long lines at a nearby tourist attraction, I began to wonder: does the venue have an obligation to take care of those people while they wait to get inside? In other words, is there some rule — written or unwritten — that says they need to provide water on hot days, or protection from the sun? And how big of a line do they need to accomodate? This certainly isn’t my area of expertise. But I’m guessing that even if the law doesn’t stipulate what’s necessary, common sense and decency should provide a reasonable guide about how to treat those people that are queued up outside your business.
