Welcome to FT, Stu Siegel!

I'm not sure what notification you received, as your link doesn't show. Also, I'm not clear what blue collar has to do with anything, and $750 for a return F ticket can be very expensive or very cheap, you don't say where you were travelling from and to.

You could have asked for as many drinks as you liked. I'm sure the cabin crew would happily have obliged (though I was not there). What difference does it make whether there are four or five rows? I'm not sure I follow.

There is always a risk of a plane swap which may or may not have the seats that you expect. There is no recourse to DL as this would have been made clear in the terms of your booking. You may get a gesture of goodwill from the airline (a few miles), but the reasons you list do not qualify for a refund. Complaining to the FDA sure is a strange one. Was the food unfit for human consumption?
