I was at the front of the line of my party of 8. Everyone received their car before me, so i tell them all to go without me and that my car should be p soon. I check on the status of my car after ten more minutes and they said sorry, forgot to give the keys out for pick up. Upset that I pre tipped and had to wait a ridiculous amount of time while the valet drivers stood there singing.
