You talked to people, overcame objections, tried to turn upset people into people willing to listen- sounds like you had the position we commonly call "public/ relations, services, advisor, etc"- or in communications -
typical job description--
The Public Services Associate provides research assistance and instruction to library patrons by staffing the reference desk; also provides customer service at the circulation desk as needed and oversees student workers staffing the circulation desk. Assists with interlibrary loan and technical services processes as well as special projects as needed.
The successful candidate must have experience with and a positive attitude toward public service work. Ability to clearly and succinctly communicate in both verbal and written (including email) formats with a diverse population required.
I would also recommend sales- if you can sell cars, appliances, clothes, whatever- they don't care if you have an 8th grade education--
