<human>: Provide a brief overview of the text.

Is it just to get the person to go away and stop bothering them? I mean if the complaint is legitimate, then yeah it should be fixed, but what does upgrading really do aside from allow more complaining over stupid things that were probably the customers fault to begin with? It just seems like complaining won't really get you all that much and in the end the staff will think you're a dick and just mess with whatever upgrade they give you even more. Same goes for just asking for upgrades too, doesn't seem like they have much incentive to give out freebies out of the kindness of their heart, unless you're hot or something.

Maybe my view is just shaded on customer complaints as I work medical. When patients complain about appointment availabilities and crap like that to the front desk people, there's nothing they can do, there's no sneaking them in or giving them a luxury doctor upgrade, it's basically just "sorry, this is what we got".
<bot>: What is the incentive for companies to help out people who complain, is it really public image? Seems like they could just forge it.
