Phone call: I was in earlier and I think I left my check book on the second floor by one of the computers.
Me: Okay, do you know which area you were in so I can go check?
Phone call: Just ask the young lady who was helping me.
Me: Its just me at the moment and I don't know where you were.
Phone: I was being helped by a young lady, have her check.
Me: Sir, there isn't anyone else here, and if you want me check, then I need to know about where you were.
