I don't mind it, I think it's a nice touch.

2 weeks ago I was flying SQ Suites JFK-FRA, and I arrived at JFK about 2 hours before departure. As I was walking towards the suites counter, I wasn't even halfway there before I heard the bored looking agent light up and say- Mr. XXXXX? I ask her how she knew and she explained that there was a very light load in suites that night and I was the last passenger to check in. I understand how she knew, and I think it was still a nice touch. I don't mind it.
