We came in for ONLY an alignment on the car. Had an appointment at 11:20am and wasn't informed how ridiculously long they're going to take. Waited for almost 4 hours!!! Toyota employees could've at least mention about the waiting time to me and rest of the customers. I would've went home to eat, sleep, wait in line at the DMV, travel half way across the world be back and maybe they might be done or not.
