what is the most disgusting thing you see or know about speech language pathologist and the pros and cons of the job

What is the most disgusting thing you see or know about speech language pathologist. When a SLP does swallowing, who inserts the feeding tube- the nurse or the SLP? What area do you work or planning to work after graduate schools (school, outpatient, hospital,)etc.?
How do I gain experience to know if SLP job is for me? I already did volunteer in outpatient and hospital, but I feel that I need a job closely connect to them to be able to know truly if SLP job is for me before investing in time and money for school. I am 26 years old and have a bachelor in education. I do not want to wait any longer nor I want to rush things too soon before I regret the job. I hope to get a job related or work closely with them for at least one or two years before making that final decision. What jobs are out there? thanks for your input.
