"I'd like Wamu to not be surprised when they file for bankruptcy".

Since we don't really know for a fact this will happen, this remark seems fairly petty. Cracks about bankruptcy really aren't funny and I wouldn't wish it on any company as it seems to be the employees that end up being hurt the most...and most employees really are pretty hard-working people.

However, I would have been offended had I been dismissed - while being polite and reasonable - by someone clearly not doing their job. Since the manager apologized (as the OP stated below), I'm sorry the OP has decided the whole company's attitude is comparable to that of one irresponsible employee.

More specific information is needed before Washington Mutual will be able to address the issue, I'm sure.
