I got a £50 gift card from work when I left for maternity leave - I've just gone to spend it and there's no money on it! I feel super awkward asking the lass who sorted it out about it, but I don't see what else to do, other than chalk it up to a loss 
I didn't keep the receipt that was in the gift card, so if it's gone out of her account, then there's no tracing it I assume? She's lovely, so I'm worried that a) she'll be mortified, and b) even if it has come out, she'll just stump up the £50 herself and put herself out of pocket which wouldn't be right.
