Amen to that! I once emerged from the showers with multitple cuts on my face, causing much concern to the spa front desk attendants! That said they were going to report to management that the razors were "unsafe" which I found rather amusing (insofar as it was obvious that nothing would happen).

I'd just grab one from Boots en route to the lounge if it were me: That should only add 5 minutes diversion.
