How often does that GPS actually drift on you though? We ran into something similar last month where the screen said we were dead on but the laser caught a 6 inch difference over a 200 foot run. Turned out the base station had moved just slightly after a truck clipped the tripod. Do you set your control points fresh every morning or are you trusting what was shot the day before? Curious if the freeze was a software thing or if the unit was just getting bad corrections all along.

Which fill are you talking about exactly, like the one right before the sax kicks back in or somewhere else? I've listened to that song a million times and now I gotta go back and really hear it.

That mac and cheese detail hits home for me. I worked at a diner in high school and we had to swap out anything on the buffet line every 45 minutes, no exceptions. If that tray was crusted over after an hour and 15 minutes, the kitchen staff either forgot their timer or just didn't care. Did you ever flag down a manager about the salad bar thing, or did you just pay and leave?
