This helps us a bunch Journey. Similarly helpful to Sting's "This book you all play at is going under, ... but I can't tell you who it is." "This book pays faster than any others, ... but I can't tell you who it is." Why bother?
That stuff is kinda silly. Who really cares if a book takes 3 minutes of an hour to complete a transaction?
Fact is a book that's busy servicing lots of customers should take longer to complete a transaction than a book with a lesser amount of customers to handle.
Which is a good reason to consider a smaller SOLID shop - WITH GREAT customer service - and yes there are many!
