Hasn't been that great lately (say last 3-4 months) for us, during the week day mornings.
Typically, ten minutes wait at those times has been the max. So it's okay, but not as fast as it used to be.
However later in the evening , its pretty empty and through in 2 minutes max, with bags.
But we only go through there once/twice a month.
I believe there are statistics somewhere on wait times, but I have no idea what they are.
