How did people heat food at work before microwave ovens?”
They either used the office toaster oven, went out to eat, or packed their own lunch that didn’t require heating. I’ve always worked in offices that had microwave ovens, but none of my schools (elementary-high school) had microwaves. Before they were commonplace, people did the following: 1. Packed their own lunch that could be eaten at room temperature (such as sandwiches), or packed it in a thermal hot/cold container. For example, my Mom would pack hot soup in a thermos for me, and I’d eat it at lunch–it would still be fairly hot. I also had an insulated pack that kept other items warm or cold (depending on the temp that they were when packed). Salads stayed cold, etc. 2. Toaster ovens: A lot of cold/frozen items can be cooked fairly quickly in a toaster oven. My offices have always had one in addition to having a microwave, and it’s preferable for a lot of quick lunch meals (such as leftover pizza). 3. Go out to lunch or eat in the company cafeteria. Microwaves have changed the way
