Answer:
The bank has to face these extra costs because they need to comply with the law, if they don't, they can face steep fines and public backlash.
Step-by-step explanation:
The fines for violating ADA standards start on $75,000 for the first violation and $150,000 for any subsequent violation.
We are all equal under the law, therefore everyone, including banks, should follow the laws and if they don't then they have to face the consequences of their actions.
