At my previous housing co-op, the new kitchen manager accidentally ordered nine cases of limes (~$1000) instead of 9 limes.
They assumed it was a mistake and only delivered a single case, which was still 180 limes, but at least it didn't use up our entire food budget.
(Normally I'd expect a phone call or email to confirm, but this was a smaller, local supplier, so they probably didn't have real systems to deal with outliers.)
