Horrible...no customer service at all.
This used to be my go to spot for smog till now. Pulled up and nobody came out for 5 minutes, I began questioning if anyone was even working. I pushed open the plastic curtain to the booth and looked at the young man sitting in there to let him know I was there. 5 more minutes and still nothing, so I again push the curtain to get his attention again. Still nothing after another 5 minutes.... Not even, "I'll be right with you". Will not return.
