WTKR reports Aspen Cline and a friend were celebrating her birthday by riding around Anthem, Arizona, and the girls decided to swing by Starbucks for coffee. However, they were told they couldn't be served on horseback in the drive-thru for safety reasons.

The Starbucks location said that had Aspen called ahead they could have made arrangments to serve her but that the drive-thru was for cars only. Aspen left disappointed that she couldn't get her birthday frap or some whip cream for her horse especially after there are several videos on youtube of people on horseback being served at other Starbucks locations.
