Danny,
I think that the GMP Controller could be on "automatic".......However,
As a "Ground" assistant, it's amazing how many Arrival ATIS are called. To be fair, a lot ["most"] Aircrew obtain the [D]ATIS when "settling in", and perhaps 10-20 mins later call for clearance, and guess what, yup new DATIS is in operation.
Don't forget, correct info twice, is better than wrong info once....
