I found out on Thursday that the T2 security closes at a certain point of the night. Unfortunately, I found that out after I had already walked outside from T1 to T2 for a flight out of the E concourse, then had to go back to the middle of the B concourse to go through the checkpoint and then back over to E once airside. I asked a grumpy-looking lady TSO what was up, and she just scowled and said "the checkpoint's closed, can't you see the sign?" so two undercover cops (in civilian clothes, but with badges on chains) told me where to go.

Reminds me why I hate that airport. Ugh.
