Just had one of those today, with the old "IT support for the wife" gig.
The missus called and asked me to log into her email and check for a mail. Gave me the password...
1st attempt: failed. Maybe I mis-typed it.
2nd attempt: Failed. I am sure I have it right. Check with the missus, get her to spell it.
3rd attempt: Failed. Email account locked.
Queue me getting blamed for locking her account for a good 5 minutes before she says......
Oh sorry, that was wrong password. But you STILL locked out my email account so it's YOUR fault....
<sigh>
