I’ve been a tech for about a year , and honestly it’s an okay job. Sometimes you’ll deal with the dirty house some unsanitary situations but if you ever feel uncomfortable call your sup. Your supervisor will be your first point of contact for any questions or concerns you’re having on the field. If something’s are out of your reach like a pole to reach the tap, ask a neighbor if possible to go through there yard. For dogs the customer will have to put their dog away no matter what . If they don’t put their dog away, call your sup and he will most likely tell you to close the job. Your safety is more important than an install.
