"the two-person support team had gone on holiday, at the same time and together, and wouldn't be back for a fortnight!"
Reminds me of the rather useless IT team I've mentioned before. Firm believers in POETS Day, they apparently assumed the repairman they'd called was too. He wasn't, and IT hadn't bothered to tell Reception they'd called one out.
So I had to search a half empty office to find the one faulty PC out of two hundred.
