@d4d25d16 I was going to ask if it was Trump University but that closed down years ago and also you said prestigious, so it seems unlikely. 

Jokes aside, sounds like a shocker, hope you get paid. It's it the first time you have spoken for them? Does this happen regularly with other places you have spoken at? Pity, it must leave a sour taste. 

 @18334f1d This happens constantly. The top ivys are often the top offenders. One spent a year trying (not) to process my reimbursement.
