Sonic Drive-In review: service

We Got up to window after ordering drinks at 8. .07 am on a Sunday morning.Gave Taya the teller $20.15 for two drinks and she told us she would have to find the manager to get change. Sit there a good three or four minutes before she gave us change and then had to fix our drinks. She could have fixed our drinks while waiting on manager and you would think they would have chage for a twenty in their drawer
