Depending on the amount of money you have in Wachovia bank, you will receive a variety of different services. The lower-tiered customers are charged $7 to use a teller but can receive the same services for free if they use an ATM. Charging low-tiered customers for using live tellers is Wachovia's approach to:.a) getting the lead out.
b) letting customers opt out.
c) tailoring offers for these customers.
d) soliciting feedback.
e) offering better services.

A, getting the lead out

Explanation:

The idiomatic expression to get the lead out means to move along quickly or as fast as possible.

Wachovia bank uses the tactics of charging $7 for teller use as a way to discourage lower-tiered customers from coming into the bank to enable the bank business move along quickly. This means that only higher-tiered customers are encouraged to use live teller services as it is believed that they are of higher value than lower-tiered customers as a result of the large amounts of money they have in the bank.

I hope this helps.
