Sometimes it's hard to tell why upgrades don't happen. Suppose I (a LifeTit!) have a reservation but I've not yet arrived. Maybe the hotel blocks me a suite but that shouldn't take that room off the market if someone wants to pay for it, so the suite shows as available. Now a Plat comes along to check in and sees that he doesn't get an upgrade but doesn't know that the hotel is holding the upgrade for me but still hoping to sell the room. Is the Plat right to be angry about being denied? Would I be right to be angry if they upgrade the Plat because he arrived first?
