I think this is dramatically overstating the daily visitation and potential sales of this bar. Sure the fire department occupancy sign is 276, but I can't see how they'd get more than 100 customers in there at a time.
There's six banquettes that seat six people.
36 Seats.
There's six tall table tops that could host six people each.
36 Standing.
There's the actual circular bar that has no barstools but could accomodate about two dozen shoulder-to-shoulder.
24 Standing.
That's 96 people, but let's just round up to 100.
In this panoramic photo of the crowded Cantina, we can see
46 customers standing, plus six CM's working behind the bar. Let's assume all the banquettes are full and there's 36 people sitting who are blocked from view by all the people standing. That gets you 82 people. Let's also assume there's 18 additional customers standing in back corners and off camera, or maybe they're just short or are bent over tying their shoes, and you get to 100 customers in this crowded bar.
(And yes, I counted the small child learning about cocktail science in the lower right hand corner)
But let's just inflate that number even further and say you could cram 138 customers in here at any one time, which would get you half of the maximum fire capacity of 276. That would net you exactly one half of the financial figures based on the fire capacity, so you're really looking at $100,000 per day and only $35 Million in sales per year.
So no wonder Mr. Chapek is in such a panic and is cutting the budgets on everything; after he pays the $15 an hour bartenders and the supplier of all that cheap grain alcohol and fructose syrup, he's probably only netting $25 Million per year from his Cantina! Mr. Chapek should set up a gofundme just to keep his 401K topped off, as he's no spring chicken.
