I think I'm getting to the point of having just no more tolerance. I run the shop and much of that duty is cutting keys. We cut a LOT of keys and some are made of nickel silver which is a harder material than brass. We've had a cutting wheel that is getting dull and makes more noise each day. About a week ago I told the office manager to get a wheel. Today I'm cutting keys and I'm just burning them, not really cutting them any more. In fact one set of keys I was cutting was getting hot to touch. So, I asked the office manager when my new wheel would be coming in and he told me that it was over a hundred dollars and the boss had to make that decision. I told him get me a wheel or get someone else to cut the keys. Things are not that tight and some decisions are not hard to make. I'm working with amatuers.
