They don't accept appointments for lab work. So, you have to get there and hope the line isn't bad. We got there, checked in and were told it would be 1-1.5 hours.
2.5 hours later, the 3 minute test was completed.
Now, while we were waiting, playing games on our phones, we heard the wait time estimation grow and grow. One gentleman made a comment that didn't catch my hear, the worker lady laughed at him/what he said, he grew rather angry. He observed that laughing at him was not very professional and was quite rude. She replied that she agreed with him and if he could get them more help by complaining to management to go for it, but she knows nothing will happen, so she laughed.
If we have to go here again, we will try for a late, late night stop during one of their few 24 hour days to see if that can speed up the visit.
