I think we are missing the point of AF's post.
How much is too much to order from ONE bank?
I think these are some indicators....
If the delivery guy has to make a second trip with his dolly just for you, he is bound to complain, and the complaint will trickle down.
If the girl tellers have to make more than 3 trips carrying your swag to the counter, they will begin to gripe, which will find it's way to you.
A manager that is bothered by too many gripes has very little patience.
Tellers that are unhappy are bad business for you, sooner or later.
