I was visiting from out of town and wanted to test with an agency while I was staying in Vegas. The one model I booked cancelled the day before our after having scheduled it weeks in advance. Apparently she didn't realize when her flight out of town was.
The other two models the agent sent me never responded to my numerous emails. The agent then said he would book someone else and he never got back to me either.
Unprofessional and a complete waste of time.
