A few weeks ago I was tidying my office at home, when I managed to snap all the supports on my stacking paper trays. This was very sad as part of the support remained inside the tray and I couldn't get it out, while I had no way of separating the trays (they weren't the kind that lock together.
Today I purchased some new trays, thinking I could use the old ones at school in situations where I didn't need them to stack, but needed to keep stuff together. Anyway, when I got home I had an idea, and so I headed to the hardware section of the local market, with sample in hand. I showed a few people what I wanted and a few said no, so I keep looking. Anyway, one man pointed me across the aisle to a lady who was selling all kinds of hinges, and door fittings. She very quickly found some door hooks which were exactly the right diameter, pulled out a pair of bolt cutters and chopped of the ends to the correct length. Perfect, so I got her to do another seven. I probably paid foreigner price for it, but it was worth it to be able to use the file trays properly, saving valuable bench space in the classroom, and these won't snap in a hurry!
