Every bank has to hire a group of people to obtain a balance in working of the facility. There is no possibility for the bank to operate with just the owner as the only representation of staff. These are of course the basics that everyone is supposed to know, but getting a bit more into the details of how a banking facility operates, you will see how distinct positions vary and how various objectives units of staff have to cope with. One of the most responsible functions of a bank employee is to keep an eye of the reserves in the strongbox - the Gold bullion reserves in many cases. Gold bullion coins are often stored In strongboxes. The times when silver bullion was there instead of gold bullion are gone, now it pays of the most to convert all the resources into bullion coins to save a lot of space. It is easier for the people who are responsible for bullion coins to keep an eye on a single room instead of watching over a couple of rooms filled with cash in form of banknotes or whatever else. It takes quite a lot of effort to do this job and be successful. The danger and the level up to which the responsible person risks to is very high. Falling asleep is not the best idea in this case - constant awareness of what is going on is necessary.
