Re: The most worrying?
Ah, asset tags. My employer is a subcontractor in an outsourcing contract, so some of the equipment in the customer's datacentre belongs to us. The lead contractor don't appear to understand this, so on a semi-regular basis they send a team of badly-shaved monkeys in to the datacentres to proclaim their ownership of all of our equipment by placing stickers over the inlet grilles to the cooling fans.
