Early In my second ever programming job I decided I needed a table in addition to my desk. This company operated on a shoestring, so my manager turned a deaf ear to my table request. SO I took a cardboard shipping box about 30x30x30”, laid a piece of plywood on it, and voila Viola! I had my table, rickety but serviceable.
A few days later my boss came by to instruct me how to deal with some issue. As he talked, he sat down on my “table”, collapsing it beneath his bantam weight, dumping him onto the floor. I got my real table two hours later.
