A respectful reminder

While maintenance is coming close to an end, please don't expect it to go the way it's intended to. Save yourself the trouble if you can and get sleep if it's late for you. If they extend maintenance, it's obviously for good reason. It's more work for them when they have to extend it and nobody wants to work more, so do be sympathizing and respectful.

If possible, should it be the case they extend it, please instead say "Thank you for your hard work".
