I totally agree re "contributing to a bank run" feeling shitty, but you have more obligation to your employees (especially), investors, and customers IMO than to your vendor (the bank). Congrats for being able to cover the payroll regardless, though.

(I am pretty confident there will be at least 250k + 50% advance-dividend early this week, and still optimistic but far from certain that a buyer will take the whole thing and it will be 100%. Last time people actually took losses of 50% above the FDIC amount (100k at the time) was 2008 (IndyMac).)
