I currently work for an Office Depot/Office max, I have a lot of experience with working with customers in terms of getting projects of theirs done in a concise and reasonable manner, and correcting any errors made along the way, or making changes they request at a moment's notice. I am trying to get out of there, because there is no future for me there.
Prior to that, I worked for a Jimmy John's, both making and delivering sandwiches, when I got offered the job at Office Depot, they were really sad to see me go, and they wish they had kept me around. I left due to the Office Depot opportunity.
Long before that however was Cicis pizza. It was where I started, and developed my outgoing customer service personality. I started as a dishwasher, and worked my way to stock when the previous guy called out sick, and it stayed that way even after he came back, and left. I left that job to finish High School.
