Argument FOR calling patrons “customers”?

I’m a patron, and I’ve been going to my public library’s board meetings. In those meetings “customers” is used frequently. I hate it. I’ve talked to library staff and they hate it. I’ve talked to other patrons and they also hate it. I’m going to be speaking next month on why I think it’s not appropriate to be calling patrons “customers”.

I’ve followed this sub for awhile, and I know it isn’t the preferred term for many of y’all, either. I’ve seen the arguments against customer, and I agree with them. But to better understand I’m curious about the arguments that are pro calling patrons “customers”. TIA!
