Basic Maths here..... Between the hours of 9 to 5 (8 hour shift), you could pour 1000 bars a day.
Demand goes to 5 times current supply (Not 40)
How many extra 8 hour shifts can you put in a 24 hour day.... The answer is strangely enough 2.
So if you have an increase in demand to more that 3 times shift capacity, putting on extra shifts is not going to solve the problem.
In the example above, with 5000 bars demand and 3000 bars capacity (in 3 shifts) , you are going backwards 2000 bars a day. Would you stop taking orders, or would you blindly ignore the problem?
