Dole,
Sure, that would be the expected thing to do, but I'm sure some employees (like supervisors/team leaders) would possibly be expected to work the whole operating day. I've worked several 18-hour O-Cs before (not by my own choosing, either). I'm sure we could all tell you about staffing levels too (hey Dave, care to comment? :)) BUT on the other hand, from a guest's POV, it's a cool idea!
