Serving Customers with Mental Illness

Another stressful day at the bank! My aunt would recount the horrors of a teller suspiciously inspecting her up and down, giggling and chatting with her co-workers about what a bad person she was.  My aunt would then explain to me how the bank no longer liked her since she started withdrawing from her account, and she feared they would no longer want to accept her as a customer.  Maria would retell the experience most convincingly, explaining to me how the staff stared at her, causing the customers in line to glare with curiosity and caution.  By the end of the conversation, I was so angered by how they treated my aunt; I decided to call the bank manager and report the teller.  I wanted to ensure that they would never treat her like this or anyone again —after all, she was a loyal and valued customer.

As the years went on, I realized the complaint phone calls that I made for my aunt about rude staff, might have resulted in a lot of decent employees getting reprimanded for actions they had never committed.

My aunt was diagnosed with schizoaffective disorder in her 50s, and the lightbulb in my head went off.  Perhaps the incidents she disclosed were based on her fears of persecution and that they had never occurred.


When she got older and could no longer live on her own, she moved to a nursing home which she liked.  However, again, she thought the administrators would kick her out on the street, and her roommate was part of the conspiracy.

Her whole life was built on fear.  Fear of every sort.  Fear every day.

Sometimes, you will encounter people like Maria, whether you are a public service employee or a customer service representative.  People suffering from hallucinations will likely be the most difficult to serve. You want to make sure you do not aggravate or trigger their fear.

Regardless of how challenging people with severe mental illnesses can be to serve, it is important to recognize they are also customers with buying power and deserve respect and equitable service. Not only is it the right thing to do, but it is also the law in Ontario.

Here are a few tips to keep in mind when serving customers with severe mental illnesses:

  •  Although you may be in a position of power in your role, try not to emphasize your authority but instead act as a helper, assisting them to find the product or service they need.

  • Establish a rapport with them, by saying their name if you know it.  Please give them a simple compliment.

  • If someone is delusional, don’t try to correct his or her hallucinations.  Avoid taking on the role of the therapist.   You can try calling their name a few times to see if they can refocus on why they need your service.

  • Occasionally, a person with a severe mental illness may threaten others.  Be aware they rarely carry them out.

  • Avoid drawing unnecessary attention to someone acting out or behaving differently.  It is disrespectful to do so, and staring at or making loud comments to them does not help.
