"Key Holder: You will be given a set of keys to the centre. With this comes the responsibility of ensuring the security of the site whilst we are closed. Duty managers will be the first person on site in the morning, and the last person to leave in the evening."
Not only do you have to be first in and last out when you're working, you have to mount security patrols when you're off duty!
