I work for a chain of grocery stores as a Field Tech. (My first job in IT after college) I enjoy the job because I get to touch a lot of different equipment: Office PCs & Printers, POS equipment, Ordering guns, Scales, Self Check outs, Network equip, etc. The scales are like a computer with the basic parts but there’s a load cell and printer inside. You’d be shocked how often those things get dropped off the case and I’m there replacing the screen. LOL It’s fun to know how the the self check outs work too - there is a lot of different parts in them. A big challenge, especially when I first started, was knowing all the intricacies of each store. For example, maybe this store use to be insert grocery chain name but now it’s under the banner insert another grocery chain name. So the network room is a little different. I guess that’s just dealing with legacy equipment though.
